Thanks for this video. I am always telling people that the bargain priced meter is not really a bargain because you will end up having to buy the SSpro2 as well. But I fear that I sound like a snob so it's good to have a clear explanation. I used to have headaches and feel anxious in places where the (consumer models I won't mention here) said everything was hunky-dory. Not only did it it cause me to doubt myself but it made other people doubt me. With a combination of the SSpro2 and Gigahertz Solutions meters I have become confident that I am consistently able to sense what the "normal" supersensitives can sense and I'm not making any of this up. I am delighted to have a better answer than "that meter isn't very good" when talking about a particular meter (People say "well reviewed" about meters meaning they got more than 4 stars on a purchasing platform!)
The number one selling 3 in 1 EMF meter on Amaz_n, and five star rated, which displays all three modes on its screen at once, (won't mention name) can't pick up Wi-Fi signals unless you move right up meters in front of the modem/router. In fact, in one case a Gigahertz Solutions RF meter displayed 100 uW/m2 in a environment and this black 3 in 1 five start meter didn't register any radiation at all. But still, if you want to quantify radiation levels in real world environments, no RF broadband meter can accumulate/add up accurately and will under read considerably. S&S and GS RF meters are the best going. However, if you want to crunch real numbers a ultra fast calibrated RF spectrum analyzer is needed, with specialized antennas. I say if you are not presenting a case in court broadband meters are much faster and easer to use, and way cheaper. ...Soldier on S&S and GS.
Thank you for the passion you put into your products, seems like a new kind of dark age we are living in with so much denial about RF and it's relationship to a healthy body. I just ordered the Safe and Sound Pro II RF meter and am excited to learn how to improve my environment and living for my friends and family, also to spread the message of awareness to people in my neighborhood that refuse to recognize the issues since our governments are now issuing Smart Meters to all homes regardless if they want them or not. I was very aware of this agenda over 10 years ago and just last week I learned about the smart meter roll out and it has re-kindled my interest in this topic immensely! Just now I see you have this new product you wear like a watch called the micro, very practical for daily use, I would imagine how much that goes off the charts in a busy environment!!
Excellent, revealing topic about the accuracy of consumer grade EMF meters. The bottom line is that ordinary, perhaps non- technical people are trying to make safety decisions for themselves. Logically they know that it can’t be done without a measuring device. Unfortunately there is no value in the many “pretty” looking meters that have poor frequency responses of their claimed frequency bands. Let’s assume a good affordable consumer grade meter exists… The next challenge is… What are safe readings? Also the “dB” scale is not linear, it’s exponential. Every increase of 3dB, the power doubles. Ionizing, non-ionizing…etc., etc. Let’s figure this out‼️
WoW , I can't really belive that I had not heard anything about this wonderful channel ever before ! Immdediately subscibed ! Thanks ver much for this informative video ...
Thank you for explanation! - EMF level meters are basically toys (some better, some worse); to identify what is going on (unless you exactly know the source to compare before and after) needs a spectrum analyzer. It makes me particularly angry when those cheap broadband EMF detectors by design and behaviour pretend to be a Geiger counter (making plenty of pseudo-alarming blip or beep noises, completely ignoring the actual RF frequency). Individual EMF frequencies have very different individual effects (mechanical vibration damage biological molecules by resonance etc. - much like a magnet vibrates the filament of an incandescent lamp due to mains frequency) those should not be confused with what ionizing radiations do. In simple terms: Ionizing radiation work like bullets, non-ionizing radiation like earthquakes (resonance effects do most harm). So instead of the beeper they should better use the speaker to demodulate the signal into audio, which helps at least to make an educated guess what the received signal source may be. (Noise of mobile radio pulses, mains hum, wireless radiator meters, nearby CB station or switching power supply do sound very different when played through a speaker.) Because higher frequencies focus themselves on much smaller spots inside the body (due to varying biological structures act like bad lenses) they can locally cause more harm by increased density than lower frequencies at the same output power. Thus it makes very much sense for meters to detect them properly. The false excuse that 5G in real life anyway uses only up to 6 GHz or such because higher bands would be only useful for special purposes (controlling robots inside a hall) due to short-range is misinformation. E.g. the gesture radar sensor in a Google Pixel phone does run on 60 GHz few cm away from your face, and in the name of surveillance capitalism similar sensors are installed inside cars to cook eh detect forgotten babies and do things like gesture control and anti-theft.
Great video, as are most of those from 9CI. I own many EMF meters, including four of the SSPro IIs and numerous Gigahertz Solutions and those from Aaronia.. We use them at home and also for measuring in other folks' homes. Another mysterious aspect is that of the antenna receiving pattern, whether for the 'isotropic' or 'directional' antennas. The SSPro2 has a directional antenna that yields a nice equivalent to an omnidirectional antenna by using a 3-axis serpentine motion for 20 seconds and reading the saved MAX value. That is a great feature for which I am appreciative. However. I would like to know the antenna pattern for devices like the SSPro2 and how that plays into the dB frequency response of the meter. Microwaves are tricky! A second under-documented aspect of many meters is how the 'pulsiness' of the microwave signal is measured, algorithmically. We choose to ignore the AVG in favor of the PEAK, but the definition of PEAK seems to involve some handwaving for all of my meters, including the SSPro2. We generally believe that it is the 'pulsiness' that is the more deleterious incitant than the carrier wave for the electrically sensitive (acute) and biological systems (chronic) -- ie. a powerful signal from a microwave oven might not be as injurious as the pulsing, periodic signal from the broadcasting smart meter or cell phone. In this case, the ratio of PEAK to AVG would be lower for an 'analog' source like a microwave oven. The more detail that is documernted for these meters, the more we can perform some citizen science with them, coming up with hypotheses that a more financially endowed lab might investigate with proper equipment. By 'pulsiness' I mean either the demodulated signal (as mighjt be reported in the sound) or some of the envelope characteristics that lead to 'beats' at frequencies that our nervous or cardiac system employs (a few tens or hundreds of Hz). Thanks for all you do. Sadly, this is to remain a growth industry for as far as the eye can see.
Hello. I need help understanding what meter to get. They put an edge broadband services earth station next to my family’s home. I was wondering if it will put off RF. Could you point me to the right meter please? It would help a lot. The station is over 300 ft away. I hope that’s far enough.
This is a nice information for us consumers to make a decision when buying an EMF meter. So if I understood correctly, when an EMF device measures a signal dominant around 500MHz and outputs a power value, say 1mW/m2, the same device when measuring a signal dominant around 5GHz and showing a power value 1mW/m2, this power can in fact be 100 times more or less than the power value that is shown for 500MHz signal. Is that right ? The only gripe that I can voice about Safe and Sound Pro II is the lack of data logging feature. Why is such a solid and well-built product not able to log valuable data that it can measure and submit to the user for further analysis if he/she wishes to do so ? I just don't understand. Cornet ED88TPlus 5G released in 2022 has data logging feature. Even GQ EMF-390 released in 2019 has data logging feature. Why doesn't S&SPro II? Is it a feature not a single user wishes ?
Greetings, and thank you for the comment. Yes, that can be correct depending on the meter's actual (real) frequency response as discussed in the video. Our focus with the Pro II has been to provide an accurate, highly sensitive, truly broadband meter, with a quality display (clear and easy to read, room for all information without having to put two pieces of information on a single line). The response to these features finally being available at a competitive price has been tremendous. We have received no specific requests for data logging to date. This is actually the first. Users who have used data logging for capturing things like Smart Meters simply use the "MAX" feature, combined with the USB power "Always On" feature. They can leave a meter overnight, and in the morning, they will see the highest value from Smart Meter pulses. For a meter with data logging, what would be valuable for the log to record? Simply RF Peak vs Time? Is the Average value useful as well? Does the Time need to be set via a PC interface, so that it is an absolute time (not a relative time)? Is Geo-Location data useful in these logs? These are all possible features, and each comes with its own cost and complexity. With so few requests for logging, we have prioritized other projects for the time being (Wearable, EMF meter, to-be-announced meters). It would be great to know what features from the above list would be valuable to you, and the degree of additional complexity and cost that you feel would be appropriate for those features. Thank you!
@@9ci Thank you for the answers. I can comment a little more about data logging feature. I am all in for any type of data that the device can offer. I would like to be able to get the best out of it. RF peak vs time is a good information. However, RF power for each frequency vs time would be a better, more detailed and useful information. Average power is of course useful but the user can calculate any derived quantity himself if he gets access to the raw data. Absolute time is better than the relative time. It can be set either with a PC or a phone connection. I wish the next generation of devices to be smart. Being smart requires a few additional features. 1) Rechargeable battery (that can last at least one day with continuous use) 2) USB type-C connection for charging and data transfer. 3) PC software and mobile app (iOS and Android) and to be able to connect to the app either with a USB cable or via Bluetooth. Yeah, I said Bluetooth, it might seem contradictory, I know. But Bluetooth connection can be used to set universal time and for data transfer. The device should have an internal storage (like a flash memory or an SD card) and log the data in intervals that the user can set. Obviously, when connected to a phone via Bluetooth, measurement function can be disabled since the Bluetooth will itself generate RF. Bluetooth Low Energy (BLE) can be chosen rather than the regular Bluetooth. GPS and geo-tagging is also a nice feature. A fancy and larger display with more data shown would be good. Other meters show RF spectrum. I would want that too. How about making 3-axis RF meter ? Is it possible to make it in the same form factor as Safe and Sound Pro II ? As you said, adding each feature increases the price as well. Currently, Safe and Sound Pro II is sold for $385 and this is near the acceptable price limit for an average user like me. I want to add a little more about data logging. To increase my environmental awareness, I first bought an air quality monitor which measures 8 parameters and logs their level every minute and then an ionizing-radiation detector which measures x-rays and gamma rays. The gamma detector is Radiacode-101 and it has some very useful features. Please check their website at radiascan. In this region of the electromagnetic spectrum, we express radiation by their energy value rather than frequency. The device can measure between 50keV and 3MeV. It has a spectrum feature such that between any two times, it divides the detectable range into 256 channels and gives the power info (in this case, the number of hits) for each channel. This is one nice spectral feature. It can also output total dose (power) every second. I like this kind of features. Safe and Sound Pro II measures between 200MHz and 8GHz. For example, is it possible to divide the detectable range in intervals of 100MHz (that makes roughly 80 channels) and output the power value of each channel in each second ? If the resolution is increased to 10MHz, we will have 800 channels and we can get even more data. I am just exploring the posibilities. Safe and Sound Pro II claims to have a professional level of accuracy, on the other hand, anything that it measures is gone after displayed on the screen. That sounds weird to me. What will people do with accurate data if they are not able to process it later ? You said you had prioritized wearable meters. I really think that's the right direction ! As users who want to be aware of their environment, I like this kind of projects. But I was thinking more of a portable EMF meter rather than a wearable. Honestly, I don't think I will wear a EMF watch. But I can carry a portable EMF meter anywhere with me, hanging it on my bag. There is already a product like this. ENV RD-10 by envirosens. I am sure you know it. If you don't, please visit their website. It has some of the smart features I mentioned like PC connection and Android app, rechargeable battery, etc. But it was released 2 years ago and it has low accuracy as reported on their own website. I was going to write to them to ask if they were planning to release an improved version of the original meter anytime soon. So I like your plans about a wearable meter. Though I prefer a portable one.
Thank you for posting. Question - Could that meter that's on your wrist also emit small amount of the same RF/EMF radiation that it's designed to detect? For that reason, wouldn't it be un-desirable to have it on your wrist (in direct contact with your skin) all day / every day? Thanks.
Thanks for your question. We carefully designed the Safe & Sound Micro to not emit any EMF in its measurement mode. With the vibrate alert function enabled, it does emit small magnetic fields while vibrating at higher levels, but this only happens when there is concerning levels of RF detected. Many electro-sensitive people use this device with no problems.
Hello, thank you for the nice video. Indeed the frequency response is crucial. You did not mention non-linearity in the frequency response with respect to input power though. Not a line plot, but a surface plot should be shown, where the frequency response is computed at many different output power levels. By the way, do you have data of this kind for the Safe & Sound Pro II ? Thanks.
Hi Marco, thank you for mentioning this. Yes, we also test the linearity of response at various power levels and frequencies to be sure our display is accurate. Below is a link to a video we shared in July 0219 showing the test process: th-cam.com/video/537mqTj2Z4w/w-d-xo.html
Does the safe and sound classic 2(revised version) and the pro 2 do good for ambient rf? As in if I’m in my room I can pick up the rf coming from a smart meter(electric company claims is a amr meter and only “smart” when a worker goes by and wake up the transmitter with a remote to grab the info) but with the gq390 detect something in the 2.4ghz range and can see the pulses with the histogram.. but only when the gq390 is next to the meter. I need something that detects ambient rf as a biological baseline because even though the eifi router is downstairs there’s still rf in my room. The gq390 does not pick up anything nor will it a few feet from my iPad unless it’s a few inches from it .. so not good.. does the safe and sound 2 models do what I’m looking for?
Yes, the Classic II and Pro II can detect very narrow pulses from smart meters down to less than 5 microseconds. This is very important for measuring narrow pulsed intermittent exposure. Only the Pro II will hold this maximum reading on the display as the MAX value.
@@9ci is there a distance from said device that these meters will pick up? The gq390 dosent seem to pick up ambient RF unless very close to the emitting object, I’m looking for something that can detect my in room exposure even if the WiFi router is downstairs and the smart meter is 15 feet away outside my window
@@mechanicalmonkey7777 That is going be determined by RF level and what materials stand between you and the meter. These RF meters will capture multiple sources of RF at the same time, they won't distinguish them like a spectrum analyzer (frequency specific). However, with the audio decode ability, you may be able to hear the narrow pulse of the smart meter.
I would like to live in an anechoic environment, but in reality we catch all the reflections from cars, glasses, walls etc. and are exposed 10 times higher. Safe and sound pro2 is a good emf meter, I have it and I'm happy, but if we add all the reflections, then we get the real dose of emf, which our body is exposed
Agreed! Anechoic chambers are comfortable to us :-) With shielding products, maybe you can concentrate on the most important location which are your sleeping areas.
The human body needs the natural DC electric field of the Earth to stay healthy. Living inside a Faraday cage or anechoic chamber would be unhealthy. AFAIK the Russians even installed a DC electric field generator inside space stations to replace that natural electricity.
May I ask, whether or not FLUKE-guys produce anything "well-designed and well-tested" for this specific market niche of electromagnetic field meters, certainly including well-done microwave power density meters ?...
He’s mostly correct except for 1. RF (non ionizing radiation) has not been proven to cause health problems. If you rewind, he never says what his health problems are. 2. No RF equipment can measure that extreme range. You have to be more specific like a blood test doesn’t test for everything. 3. There is not proof that people are RF sensitive or sick. He’s trying to sell his product that has the same physics of number 2. Good luck sir. Source - RF engineer. If you feel that you are RF sensitive, where are you going to go to get away from that? Nowhere on this planet.
Cornet released a new version of their all in one EMF meter, 3rd generation ED88TPLUS 5G. It is available at safelivingtechnologies. They also put a frequency response graph on the last page of its manual. Have you had a chance to test it ? Is version 3 capable of measuring RF signals on par with Safe and Sound Pro II ?
Hi, and thanks for the comment. We have not had the chance to test the ED88TPLUS. Previous iterations of the ED88T did not perform well when we tested them at the Nemko lab using the test procedure used on the Pro II. If you are interested in the credibility of Cornet's frequency response graph, we would recommend contacting them and asking for a copy of the lab test report of their testing. If the testing was performed in a lab with certified and traceable equipment, there will be a formal test report available. We will evaluate the ED88TPLUS and other updated/new meters next time we have extra time in the RF testing lab.

How refreshing it is to see a video where the presenter can speak whole sentences without editing out something every two words.

Why i read that ionitazion could be from 10 MHz to 2 Ghz above 10 mW/m²? I thought ioniuzation depends only on frequency?

This is a nice information for us consumers to make a decision when buying an EMF meter. So if I understood correctly, when an EMF device measures a signal dominant around 500MHz and outputs a power value, say 1mW/m2, the same device when measuring a signal dominant around 5GHz and showing a power value 1mW/m2, this power can in fact be 100 times more or less than the power value that is shown for 500MHz signal.

You said you had prioritized wearable meters. I really think that's the right direction ! As users who want to be aware of their environment, I like this kind of projects. But I was thinking more of a portable EMF meter rather than a wearable. Honestly, I don't think I will wear a EMF watch. But I can carry a portable EMF meter anywhere with me, hanging it on my bag. There is already a product like this. ENV RD-10 by envirosens. I am sure you know it. If you don't, please visit their website. It has some of the smart features I mentioned like PC connection and Android app, rechargeable battery, etc. But it was released 2 years ago and it has low accuracy as reported on their own website. I was going to write to them to ask if they were planning to release an improved version of the original meter anytime soon. So I like your plans about a wearable meter. Though I prefer a portable one.
A Building Biologist (Germany) says THANK YOU!
Thank you for posting. Question - Could that meter that's on your wrist also emit small amount of the same RF/EMF radiation that it's designed to detect? For that reason, wouldn't it be un-desirable to have it on your wrist (in direct contact with your skin) all day / every day? Thanks.
Thanks for your question. We carefully designed the Safe & Sound Micro to not emit any EMF in its measurement mode. With the vibrate alert function enabled, it does emit small magnetic fields while vibrating at higher levels, but this only happens when there is concerning levels of RF detected. Many electro-sensitive people use this device with no problems.
$50k isn't too bad when it comes to test equipment in general, probably because it's more common because it's a such a capable tool.
Hello, if you know the TES-593, would you be able to tell me your opinion on precision and accuracy ?.
Thank you
Hello, thank you for the nice video. Indeed the frequency response is crucial. You did not mention non-linearity in the frequency response with respect to input power though. Not a line plot, but a surface plot should be shown, where the frequency response is computed at many different output power levels. By the way, do you have data of this kind for the Safe & Sound Pro II ? Thanks.
Hi Marco, thank you for mentioning this. Yes, we also test the linearity of response at various power levels and frequencies to be sure our display is accurate.
Below is a link to a video we shared in July 0219 showing the test process:

Does the safe and sound classic 2(revised version) and the pro 2 do good for ambient rf? As in if I’m in my room I can pick up the rf coming from a smart meter(electric company claims is a amr meter and only “smart” when a worker goes by and wake up the transmitter with a remote to grab the info) but with the gq390 detect something in the 2.4ghz range and can see the pulses with the histogram.. but only when the gq390 is next to the meter. I need something that detects ambient rf as a biological baseline because even though the eifi router is downstairs there’s still rf in my room. The gq390 does not pick up anything nor will it a few feet from my iPad unless it’s a few inches from it .. so not good.. does the safe and sound 2 models do what I’m looking for?
Yes, the Classic II and Pro II can detect very narrow pulses from smart meters down to less than 5 microseconds. This is very important for measuring narrow pulsed intermittent exposure. Only the Pro II will hold this maximum reading on the display as the MAX value.
@@9ci is there a distance from said device that these meters will pick up? The gq390 dosent seem to pick up ambient RF unless very close to the emitting object, I’m looking for something that can detect my in room exposure even if the WiFi router is downstairs and the smart meter is 15 feet away outside my window
@@mechanicalmonkey7777 That is going be determined by RF level and what materials stand between you and the meter. These RF meters will capture multiple sources of RF at the same time, they won't distinguish them like a spectrum analyzer (frequency specific). However, with the audio decode ability, you may be able to hear the narrow pulse of the smart meter.
I would like to live in an anechoic environment, but in reality we catch all the reflections from cars, glasses, walls etc. and are exposed 10 times higher. Safe and sound pro2 is a good emf meter, I have it and I'm happy, but if we add all the reflections, then we get the real dose of emf, which our body is exposed
Agreed! Anechoic chambers are comfortable to us :-) With shielding products, maybe you can concentrate on the most important location which are your sleeping areas.
The human body needs the natural DC electric field of the Earth to stay healthy. Living inside a Faraday cage or anechoic chamber would be unhealthy. AFAIK the Russians even installed a DC electric field generator inside space stations to replace that natural electricity.
The micro USB jack (Safe and Sound Pro II), is it only for power supply? Or is there also a possibility of data out?
The USB jack is just for power supply and continuous operation.
Where I can buy RF wristband detector and good RF detector that have correct response range?
The wristband Safe & Sound Micro is available at Safe Living Technologies.

정확한 RF미터를 찾는 것은 정확한 이어폰이나 스피커를 찾는 것과 비슷하다는 느낌을 받았습니다. 😀
thank you
may i re-upload this video with all your links in the the video
For sure.
May I ask, whether or not FLUKE-guys produce anything "well-designed and well-tested" for this specific market niche of electromagnetic field meters, certainly including well-done microwave power density meters ?...
im still waiting for you to tell what EMF readers u recommend to buy
I would also like to know what reader would be useful.
In the end we get "intelligent blabla", but no real answer to our question . . .
@@MichaelM-tt5wd I have recommends and reviews in many videos, real world tests with EMF meters.
3:08 me too man !
Wha cha la wha cha la
He’s mostly correct except for 1. RF (non ionizing radiation) has not been proven to cause health problems. If you rewind, he never says what his health problems are. 2. No RF equipment can measure that extreme range. You have to be more specific like a blood test doesn’t test for everything. 3. There is not proof that people are RF sensitive or sick. He’s trying to sell his product that has the same physics of number 2. Good luck sir. Source - RF engineer. If you feel that you are RF sensitive, where are you going to go to get away from that? Nowhere on this planet.
A whole lotta talking with next to ZERO information Very UN helpful.
Cornet released a new version of their all in one EMF meter, 3rd generation ED88TPLUS 5G. It is available at safelivingtechnologies. They also put a frequency response graph on the last page of its manual. Have you had a chance to test it ? Is version 3 capable of measuring RF signals on par with Safe and Sound Pro II ?
Hi, and thanks for the comment.
We have not had the chance to test the ED88TPLUS. Previous iterations of the ED88T did not perform well when we tested them at the Nemko lab using the test procedure used on the Pro II.
If you are interested in the credibility of Cornet's frequency response graph, we would recommend contacting them and asking for a copy of the lab test report of their testing. If the testing was performed in a lab with certified and traceable equipment, there will be a formal test report available.
We will evaluate the ED88TPLUS and other updated/new meters next time we have extra time in the RF testing lab.
@@9ci Thanks. I will be looking forward to your new tests. Cornet version 3 goes by the name ED88TPLUS5G.
Hello. I need help understanding what meter to get. They put an edge broadband services earth station next to my family’s home. I was wondering if it will put off RF. Could you point me to the right meter please? It would help a lot. The station is over 300 ft away. I hope that’s far enough.
