My first Geiger counter
5 Stars
My first Geiger counter
Never owned a Geiger counter before, so here are my dilettante impressions.A very interesting device!First and foremost: do yourself a favor and download the PC software from the company website to make things easier.The software makes it easier to make sense of the settings and the data.Otherwise, simply turn it on and let it work. No need to calibrate or any kind of setup.Straight out of the box: put in a battery and push a button.Done.The radiation measurements are nearly instantaneous, but wait for about a minute to get the most accurate ones.The measurements in my case tend to jump around between 0.13 and 0.18, which is normal (as long as lower than 0.30).There is a little radiation symbol that blinks on the screen every time a radiation particle is detected, gives a bit a of a good old analog feeling.I placed the device on a granite countertop in my friend's kitchen and it worked! I got a much higher measurements than I normally see.Note: do not expect these devices to work on microwaves, radon gas or Wi-Fi - that's a different type of radiation. Need special detectors for that.Nor sure what the difference is between this model and the white one they have. I have not found anything so far. Maybe a software thing? Anyways.I like that it is easy to use, compact, clear readings and not too expensive for my first geiger.The little manual gives a good reference of safe levels vs dangerous levels.Audio beep can be turned off and there is also a vibration mode, like on a cell phone.Room for improvement: no internal memory.Readings are either shown on the device immediately (like a thermometer) or can be fed live via cable to the laptop to be shown and recorded in the software.Otherwise, a solid recommendation. If you have a question - email the company, they got back to me in less than an hour!

5.0 out of 5 stars My first Geiger counter
Reviewed in the United States on April 5, 2019
Never owned a Geiger counter before, so here are my dilettante impressions.

A very interesting device!

First and foremost: do yourself a favor and download the PC software from the company website to make things easier.

The software makes it easier to make sense of the settings and the data.

Otherwise, simply turn it on and let it work. No need to calibrate or any kind of setup.

Straight out of the box: put in a battery and push a button.

Done.

The radiation measurements are nearly instantaneous, but wait for about a minute to get the most accurate ones.

The measurements in my case tend to jump around between 0.13 and 0.18, which is normal (as long as lower than 0.30).

There is a little radiation symbol that blinks on the screen every time a radiation particle is detected, gives a bit a of a good old analog feeling.

I placed the device on a granite countertop in my friend's kitchen and it worked! I got a much higher measurements than I normally see.

Note: do not expect these devices to work on microwaves, radon gas or Wi-Fi - that's a different type of radiation. Need special detectors for that.

Nor sure what the difference is between this model and the white one they have. I have not found anything so far. Maybe a software thing? Anyways.

I like that it is easy to use, compact, clear readings and not too expensive for my first geiger.

The little manual gives a good reference of safe levels vs dangerous levels.

Audio beep can be turned off and there is also a vibration mode, like on a cell phone.

Room for improvement: no internal memory.
Readings are either shown on the device immediately (like a thermometer) or can be fed live via cable to the laptop to be shown and recorded in the software.

Otherwise, a solid recommendation. If you have a question - email the company, they got back to me in less than an hour!

5.0 out of 5 stars Useful personal dosimeter
Reviewed in the United States on February 21, 2021
This dosimeter is pretty handy. I purchased it to keep track of how much radiological dose I was getting at work. While this device is no replacement for an TLD/OSD or film badge, it is nice to have one of these on hand to get a rough estimate of how much radiological dose you are exposed to. You can stick this thing in your pocket (mine goes in next to my pens on my shirt) and even set it to beep or vibrate at a dosage threshold of your choice.

The meter measures dose rate in Sieverts and I've included a photo of it running next to a Ludlum 19 (which is in micro R/hr... multiply readings on Radex by 100 to get mR/hr. Please consider the scale on the Model 19. I found the readings to be pretty close (15 uR on the model 19vs 0.16 uSv on the Radex and 171 uR on the model 19 vs. 1.57 uSv on the Radex. Next time I'll see if I can get the numbers next to a known calibration source for a better comparison.

Anyhow, I'm extremely happy with these results. I like the way the audio tone warns me when I'm in a high-dose area. This item is highly recommended for anybody to keep their dose levels ALARA.

5.0 out of 5 stars Just remember to change the batteries
Reviewed in the United States on March 31, 2021
Great little gizmo! This is my second one; I left battery in to long on the first one and it corroded... low draw devices work for a long time on the same battery but often causes them to fail by deteriorating the battery’s chemical container. It worked for about 4 years so I’m happy to buy a new one.

5.0 out of 5 stars Overall great small geiger counter, but with minor issue -- hard to use in low lights
Reviewed in the United States on March 1, 2021
Overall great small geiger counter with somewhat ~10 seconds reading accuracy .
Easy to use and easy to carry over due to form factor.
At the same time -- you will find it hard to use in low lights . When you hike or cave exploring forcing you to use light.
