As you may have noticed, the board has a bunch of unpopulated solder pads with missing components. I suspect that there were additional features originally designed for this device but were not implemented for some reason. If anyone has schematics for this meter or at least knows what these components are for, please let me know in the comments. I would be very grateful.

I'm gonna answer this question myself. I've contacted BOSEAN, and they said that the missing components are for the electromagnetic radiation detection.
Good video for setting this detector up. Just three buttons with multiple functions was giving me a headache, but now I see!
Glad I could help!
It a great device and probably the best in its price range. I made a more detailed video on this product a few months ago...
Yeah, I've seen your review, and I like your channel. From my point of view, there's still no perfect dosimeter on the market. I wish there was something like Radiacode 103 but also with a GM tube as a second sensor, IP 65, touch screen, Bluetooth. Maybe even built in GPS chip. It's not that hard to make it.
@@ElectronicsComputers Its not difficult to design what you suggest, but it is difficult to make for a price that will make it successful in the market. GM counters are being pushed down in the cost they can command in the market as gamma ray spectrometers come down in price.
If you have measured the GM tube voltage with 1Ghom resistor in series with multimeter test leads you will have about 420-414V readings. :) I have measured. :)
Do you know the resistance in ohms of the resistor for the tube?
Great review. i always hope ill find a review like this when im researching a product but rarely do
Thank you for the comment!
will it work (minus recharge) if battery terminal are switched to an external 3 AA cell pack?
@@ElectronicsComputers Ni-MH AA rechargeable batteries should be 1.2 volts. Wouldn't it work in series (3.6 Volts)? Fresh Alkaline should be 4.5 V, a bit too much I suppose, the device battery is 3.7 V.
That dosimeter requires at least 3.5 volts power supply. So, three AA battery will do the job. With two it won't even turn on.
@@danndank It will work perfectly fine with three regular 1.5V batteries or rechargeable NiMH 1.2V batteries. The latter should be recharged using a dedicated charger.
@philiptong4978 That dosimeter requires at least 3.5 volts power supply. So, three AA battery will do the job. With two it won't even turn on.
GM tubes have particular voltage range where it works as expected, too low or too high will give false reading, would be nice if the high voltage circuit can adapt to a range of inputs
Great video.
Thank you for the comment.
Could you please share what kind of software that use
You can download that software from the official website: www.bosean.net/wp-content/uploads/2024/03/Personal-Radiation-Dose-Management-System.zip
How could I test this revitalizing tonic i bought online? I can't remember what exactly is in it but the sediment on the bottom of the bottle stays warm even when the liquid is cold. I've been using it and at first I did think it helped with energy, but I've been feeling not that good and my teeth look a greyish color and feel kind of loose and my hair is falling out i think. I'm probably just being paranoid but i want to check.
If you're worried about the radioactivity of the product, you can measure it with any dosimeter. If you don't have one, you can buy the cheapest pencil-shaped one, which I showed in the video. As for your tonic, I really doubt there’s any nuclear reaction causing it to stay warm. It could be a chemical or bacterial reaction. If you notice any negative effects on your health, you should definitely stop using it.
@ElectronicsComputers it has this sand like sentiment in it that i think looks like it glows in some of the pebbles and after a uv light shinned on it they gloy like glow sticks. Its some tonic from an old abandoned barn.
@ElectronicsComputers also i did stop using it but ive been losing weight, look pail and am bruising really easily. Passing dark clots in my urine too.
@ElectronicsComputers i think the bottles says radifor or radithor or something. There's also a tin with tablets that are supposed to revitalize you.
Hello
Very nice video, thanks : )
This geiger counter is having good press lately. Manh yourubers that seem to know what they are doing are recommending it as a budget option.
I got mine a couple weeks ago. I hope I got ir for fun and not for prepping
One question if you don't mind.
I'm IT, so, I'm a noob in these matters. Recently I wanted to get two samples from AliExpress to toy with the GC. Very light, the crystals that you link and another thorium salts pendant (New age people is a little crazy, right?).
In the end I didn't bought then because I thought that I better make some research on how to handle them, store them and dispose of them shall I have to. Even if these are very light.
Can you give some advice or recommend something to read in that regard?
I'm looking into it, bur any advice would be super wellcome.
Thanks again for the video. Regards.
Well, even though this dosimeter is considered budget-friendly, it's still better for me in all aspects compared to the $500 Gamma Scout I owned, including interface, dimensions, and features. There's also firmware available source code availbale online, allowing for customization.
Regarding radiation safety, it's not about the strength of the source but the duration of exposure. You could visit Chernobyl's Unit 4, one of the most radioactive places on Earth, for half an hour without adverse effects. However, wearing a small, weak sample from a smoke alarm as a medallion could be fatal in 18 months.
Next time you fly, take a dosimeter and you'll see it go crazy at 10 km (33,000 feet) altitude, where the average radiation level is 2-5 microsieverts per hour. Recently, I had a CT scan of my thyroid with radioactive iodine injected into my vein, and the radiation around me reached up to 150 microsieverts, causing all dosimeters in the room to beep. But within a few days, the radiation was undetectable. X-ray doses range from 100 to 1,500 microsieverts. I've had dozens of X-rays in my life.
Having a collection of radioactive isotopes, which is a hobby for many people including myself, is totally safe and I just keep them in a drawer. I'm confident they can't harm me unless attached to my body or ground into a powder and inhaled. As one doctor said, "Low radiation is life, high radiation or no radiation at all is death."
I also hope to use this equipment for my hobby and not for surviving, considering current world events.
There is something wrong with this counter.
It contains a J321 tube which is pretty good for sensing low levels of radiations but goes up to 120mR/h (which is significantly lower than the 50uSv/h written on the manual!!!)
The specification for the HFS-302L tubes used in the HFS-P3 are hard to find, but at least the size of the active area (only the space inside the metal tube) are comparable to a tube that can goes up to 50uSv/h (so the specifications seems legit).
Maybe your radiation source doesn't emit more than 120 mR/h (1.2 mSv/h), which is why that’s the maximum you're getting. In my case, I tested with stronger sources, and it goes up to 2.5 mSv/h. I don’t have-and definitely don’t want-any stronger sources to get higher readings. Nor would I ever want to find myself in a situation where I’d need to measure anything above that.
@@ElectronicsComputers No, i don't have this specific geiger counter but many others instead.
Concerning the source, i have access to an X-ray machine so i can test even more than 1000 R/h without problems.
My concern is only to the J321 tube, which is rated for up to 120mR/h according to the manufacturer specifications.
For sure it can be forced to measure even higher values (using a series resistor of a smaller than suggested value) but is of course it can't be stretched too much (also is not not recommended because the lifespan will be shorter).
I think that this counter was originally intended to use another tube but was later modified by the manufacturer to use a cheaper option instead (which is for sure significantly more sensitive than the original tube but also have a significantly less range).
This is a classic thing in any cheap chinese geiger counter, when they find a cheaper alternative they change the tube and change the firmware to change the conversion factor.
And, BTW, there are some chinese alternatives available on the market for example the Pudibei NR-750, NR-850, NR-950 and NR-1050 (i.e. the exact same device available with 4 different tubes for a different performances and different ranges)
Great!!
Thank you!
