MOESAPU Geiger Counter Nuclear Radiation Detector, Rechargeable Handheld Radioactive Dosimeter with 2.4“ TFT Display GM Tube Detects X Ray Beta Gamma Portable Radiation Testing Device, FS5000 (Yellow)

Basic and nice

Easy to use but I can’t get it to “click” with counts. I’ve emailed the company with no response. If they would write back, I’d give it 5 stars. The instruction manual could be more detailed. It took a little while to figure out how the buttons and menu worked but once I played with it, it became intuitive. It appears to be extremely sensitive and, presumably, accurate. (there’s no way to validate it) but it’s certainly consistent. My background radtiation level reads 0.07 to 0.15 microseiverts all around my property. A table reviewing the medical implications of micro, mini and full seiverts would also be helpful but that’s readily available on the internet.

What else can I say. It works, got the same reading as my other counter on my uranium glass set, it clicks for particles but it can be turned off in settings. It seems durable and user friendly. Not bad for its price.

Everyone should have at least one guy your ginger counter at home. Cause you never know. Tested at the smoke detector and seems to work.

Our cat was irradiated for thyroid disease. I bought this device to check the litter box and other items around the house as her radiation levels diminished. It's easy to use and provides plenty of information and modes for detecting radiation levels. Well worth the investment.

Careful not to drop it in water, it isn’t waterproof.

I bought this one, because it got good reviews. However, I'm a little disappointed. It's slow to respond, and seems not able to detect beta radiation very well. But, it does make the clicking noise. I opened it up and confirmed it had the J321 GM tube. I figured that it would work much better with the better rad-pro firmware. However, installing the new firmware is difficult and requires a special USB adaptor.

Quick charging and easy to use with abelt clip included. It’s durable as I already dropped it once and its still functions. Good instructions with visual aids.

I wanted a radiation detector since a while, found this very affordable, seams to work well, good quality build, went to their website and chat support is 24h, they gave me a link to download driver and software, click on Personal Radiation Dose Management System from the download page, its in a zip, I posted screenshots so you can see the link on top of the page, you can set screen timer with the windows app, for the driver, run CH341SerSetup from the zip then run PRDMS V1.0 to install the app, now you can set a laptop to record the data while charging the device while travelling around and get alerted if you are exposed to radiations:D

Al principió no se por que no me quería responder el guardar del menú para programar el tiempo de apagado de la luz de fondo, pero de repente todo comenzó a funcionar bien. Recomendaría al productor que checara ese detalle de la circuiteria.

Semble fonctionner et avec les mesures qui donne je suis corect

Works OK. For a typical consumer, there aren't a lot of radioactive substances around to test a Geiger counter with. However, the meter worked reliably and usefully for someone who had had radioactive iodine treatment. The data download feature via USB is frustrating - data can be downloaded in real time, but is not saved.

I purchased this on August of 2024 and the manufacture date on the unit shows May 2024. It's a very recent production unit. First thing you notice when you open up the unit is that it uses machine screws and threaded inserts instead of self tapping screws. Most people would not notice this let alone open up the unit. It's a very good indicator of quality. Next, you'll see the Geiger muller tube. It is a J321 tube which is as high quality as you can get within the affordable range. The tube itself is also manufactured in 2024 as indicated by the print on the tube. Next you'll notice that the solder points on the PCB are quite clean and the components are positioned well. The tube itself is snapped into a clip on the board but you'll also notice some solder on the clips themselves so there is no concern of the tube coming loose when jostled. The plastics are light while feeling well made. There are no sharp edges and they line up quite well. It's not a heavy unit but it's built well. The USB port has a rubber cover that keeps dust out. The only issue I can see is that the back of the unit has open vent holes next to the tube. This is probably to help increase the sensitivity to beta radiation but can be an issue if radioactive dust/dirt get in and settles around the tube causing it to read high constantly. Data logging through the USB port is apparently available but I have not tested it. The screen is of good quality and gets the job done with clear text. The user interface is intuitive and easy to navigate. In terms of features, it includes the signature clicks that everyone wants to hear, audible alarm, LED indicator, and even a haptic vibration motor to alert you if your environment exceeds your customizable dose rate threshold and total dose threshold. It also has a graph that shows dose rate over the last 3 minutes. Overall, very pleasantly surprised by the quality and value of this unit.
