- With Infrared Thermometers www.tme.eu/en/katalog/piromet..., you can measure body temperature in a sec, from a distance! However! You should pay attention to crucial elements such as the D to S ratio, emissivity, and even the angle!
The IR Thermometer can be your friend! But only if you follow the rules :-)
0:00 Intro :D
0:50 But how do they work?!
1:28 What is emissivity?
2:05 How to measure the temperature right?
3:09 What is the purpose of a laser dot?
3:20 D:S and optical resolution
3:49 2 lasers IR thermometer
3:55 How to take care of the IR thermometer?
4:20 Something extra ;-)
Infrared, are non-contact temperature sensors. www.tme.eu/en/katalog/piromet...
The measurement is non-invasive. In order to make a measurement, a IR sensor does not have to exchange heat with an object being measured.
This way, IR thermometers do not interfere with the temperature field during the measurement, and their dynamic characteristics are incomparably better.

At last, a video made by people who understand the physics involved in the operation of laser thermometers, kudos.
This is the best video about IR thermometers on TH-cam!
Excellent presentation. Lots of essential information, And LOVED the outtakes!
Szukałem potrzebnych mi informacji i jeszcze trafiłem na polski akcent. Jak miło :D
Excellent information. Love the bloopers too.
Good job you nailed the overall use of this meter. Thumbs up to you.
So very clear! Very helpful! Thank you! 👏
Excellent explanation!!!
“Like it or not, make sure you subscribe.” Thats confidence right there😂
Glad I watched this before buying one!
Great information, very helpful
Good explanation!
very educative thank you
Thanks, that was good information.
👍😎👍
This damages the brain ..dont let them use it on you
@@uglywatchtower3299 how?
This is the best explanation
Thanks for the very informative video! If measuring a surface over a fire, how accurate are they? I'm thinking of pottery in a kiln, iron in a forge, food in a campfire, etc. If you can avoid the smoke, are they accurate, completely worthless, or somewhere in between?
Dear Tim! IR thermometers are good tools for measuring temperature from a safe distance. However, for measuring the temperature inside the kiln we suggest a pyrometer. We have selected for you a few temperature meters that are in the range, check it here: www.tme.eu/en/katalog/temperature-meters_112631/?s_field=1000011&s_order=desc&id_category=112631&search=thermometer&visible_params=2%2C1785%2C1786%2C1784%2C72%2C55%2C1747%2C2950%2C1952%2C317%2C1605%2C74%2C1807%2C82%2C1970%2C1813%2C375%2C384%2C1854%2C383%2C2390%2C2998%2C1810%2C1808%2C1594%2C3177%2C3035%2C32%2C1971%2C436%2C536%2C1967%2C885%2C351%2C1953%2C1825%2C707&mapped_params=1952%3A1821635%2C1819696%2C1821567%2C1819815%2C1819791%2C1821004%3B
Do not forget to select the proper probe :D
Have a nice day!
thx, this information so good
Verry good
We do notmeasure muffins at no time do you explain forehead or what the numbers mean as we are used to Fahrenheit or Celsius
Ever used an armeator thermometer? How's the effect
Hello, thanks for the video, what termometer I could use for measuring face temperature? ( I use it when I do my cosmetological procedures..):)
Your face will give different readings on different spots, pending on blood circulation. I would use a IR meter, but it will stil not give you an exact reading, but a reference temperature anyway.
Hello from Poland:)
But didn't the black tape affect the material and the reading especially ud the pot was hot and you put on a cold tape?
Hey :)
Yes, you can give it some time and let the temperature stabilize.
Overall, low emissivity objects such as shiny metals, emit less infrared energy and this can be a challenge for the IR thermometer. To get a more accurate measurement you can apply black tape or flat paint to the shiny surface, wait a bit and then measure.
We hope it answers your question,
Have a great day!
What should emissivity be set to for a cast iron griddle?
Hey Jim, that's a great question!
The emissivity for cast iron is between 0.7 to 0.9.
For better accuracy, you can measure with an IR thermometer and a probe. Then, set the emissivity that will give you the same temperature. We hope it answers your question.
Have a nice day!
Lady - the temp o n the coffee cocker - if went UP - NOT because if the emissivity of the tape, but becasuse, the black tape has BLOCKED some degrees ( for a while ). Hold it there for a minute - reading will ba SAME ! 🤷🏻♂🤷🏻♂
Notice! Those IR thermometers are not indicated for medical uses.
Range too large
Yes. The temperature of an industrial IR thermometer can range from -50 up to 1000 centigrade and even more. Therefore the accuracy is +/-1 deg which is enough for industrial applications. On the other hand, medical IR thermometers have much lower range between 32 up to 43 centigrade and ten times the accuracy of an industrial IR thermometer.
None of them are for medical .This damages the brain
@@uglywatchtower3299 how!? how does a passive device damage the brain!? do you know what passive means?
@@jaqssmith1666 Sickening, isn't it? People are so completely brain dead.
Please does this thermometer have internet connectivity?
Hello there!
Unfortunately, this particular one doesn't connect with other devices. Actually, most of them are "offline" BUT! There is one in our offer that does connect via Bluetooth with smartphone. Check it out here: www.tme.eu/details/testo922/
Have a lovely day! 🐸
What a cute smile
How many degrees should you add for an actual body temperature?
Or not add any at all?
Dear Fire Goddess, that's a wonderful question. But before we answer, we want to emphasize that those IR thermometers are not for medical purposes but for measuring the temperature of surfaces in a workshop, warehouse, HVAC, etc.
The accuracy of the measurement can be found in the specification tab under the "Non-contact temperature measuring accuracy". With this information, you can calculate the divination from the real temperature.
For example, the FLUKE 561 IR thermometer has an accuracy of +/-1% or +/-1deg (whichever is greater).
This means that for a normal body temperature, 36.5deg, the measured value can range between 36.2-36.8 (for +/-1%) or 35.5-37.5 (for +/-1deg). In this case, the higher deviation is +/-1deg and hence a normal body temperature can be identified as fever (37.5deg) :/
We hope this answers your question and we wish you a wonderful day :-D
@@TME.ElectronicComponents oh okay. The one I have is for medical use lol. So sorry.
Why doesn't it measure the air? Doesn't it radiate?
It does, especially if outside. They’re not ideal but they work for most indoor screening.
@@onisti2635 No, it will not measure the air temperature at any temperature. It does measure some gases in the air, CO2 CH4 H2O vapour, but, they are trace gases. It does not nitrogen or oxygen, 99% of the dry atmosphere. And if you think these gases have something in common with what are termed the greenhouse gases and non-green house gases, they are in common. John Tyndall used the thermopile, the same as used in your device, to determine what he thought to be, and we still think are the greenhouse gases. He was wrong, we are wrong. They are the thermal electric and non-thermal electric gases, that's all. Oxygen and Nitrogen have emission spectra lines in the infrared and these are inferred by the Raman spectrometer. This is my discovery, no scientist enjoys what I have uncovered, I wonder why? Any ideas?
@@fractalnomics it’s been 108-110 where I live and we get screened outside, we had to stop using the touchless ones because they were reading everyone at 108-110. I’m no scientist so idk if it’s gasses or what, but I do know they were recording everyone at 108-110 for the couple days it was that temp here, so we had to go back to under the tongue readers.
@@onisti2635 Hi, we have to distinguish thermocouples from thermopiles, thermopiles are many thermo couples in series. Thermocouples are used in screeens and under touge, they are good and accurate. Not so from thermopiles, as used in the IR 'gun'. They will measure the screens, but not the 'air' directly in front of the thermopile detector, that's my point. Btw, they, thermopiles, don't measure (very well) the solid metal (metalloid) germanium either. By these substances all have a temperature though.
What a CUTIE!!!!!!!
Hello from Bulgaria
Hello Biser Hristov, thank you for being with us!
Additional point: never point the laser at someone's eyes.
0:43 Should have split: IR Thermo - Meters. Makes more sense, if you absolutely had to split it.
Dear Ovidiu-Florin BOGDAN, thank you for this comment. We will pay more attention to it next time. Sometimes the things are so obvious that even if they were under your nose you won't see it. But fortunately, we all know what the video is about :)
They’re good for troubleshooting, but not good for accurate temperature readings..
Why cant they just scan your wrist? This way you're not feeling so damm uncomfortable not knowing if this is hurting you?
Because it's about control and yes they can scan wrist but some people abuse their authority and are power tripping!
she has been paid to say this ...This damages the brain
@@uglywatchtower3299 How?
Because you’re wrist is generally a lower temperature, even if you have a fever. So if you have a fever but get scanned on your wrist, it may not show. Forehead is generally more reliable. And just so you know, they don’t hurt you. All they do is absorb the heat of whatever is around it, which is why they’re not ideal especially in hot and cold weather.
@@onisti2635 interesting because now there taking temp on the wrist. So we should tell them they are wrong according to you?
dang whay accent is that south africa?
Polish lmao
I thought the laser is for cats. 😀
If my employer scans my forehead/brain every day, am I getting radiation? What does this do to my brain, I heard some get head aches, and could this cause brain cancer?
no, the energies are too low to do you any harm.
The device is measuring (heat) radiation coming FROM YOU. It is not emitting radiation to your body.
@@betterthanyesterday6292 Accumulative.
@BonTheGreat They don't emit anything. There is no risk.
@@VickiTakacs. What is accumulating?
they aint using this shit on me
They used this shit on me, now I suffer from acute memory loss!
why
@@SeriousSchitt nope
It is indeed harmful for your pineal gland
It works in the same way a normal camera works moron 🙄. You just can't see the light but just like a normal camera the infrared thermal measuring gun is just a camera that measures heat.
nope
very thick accent, couldnt understand one word
Difficult to take a young attractive woman seriously but in spite of my very mistaken knee jerk bias you present yourself as credible. At your age you might be undermining yourself by showing the bloopers.
Relax Craig, she’s an old lady now, that was 5 years ago.
you need to touch more grass sweaty
Depends upon the target audience.
