Geiger Counter Radiation Measurement Instrument Gamma (γ) Radiation, X-ray Radiation Measurement Instrument LCD Measurement Accuracy 0.01μSv / h Nuclear Radiation Detector Data Logger

I became skeptical of this geiger counter's ability to actually detect radiation when I held it near a piece of Uranium ore and it did not react. I also noticed the reading of mili Sieverts per hour appeared to fluctuate at complete random, never going above ~0.25 whether it was in a radiactive environment or not. I purchased a high quality one and conpared its (much more detailed) readings to this one and the difference was clear. It reacted quickly to the test material while this one did not. In conclusion, it does not seem to work accurately, it may not even work at all. Do not put yourself at risk by buying this device, your safety is worth the extra cost of a high quality geiger counter.

I believe this was a returned used unit sold as new. It had scratches, very slow response time when exposed to sources and the screen came,with a single led line burned out on it.I returned for full refund. I advise spending a little more money on a better unit.

Good

It was showing background readings of just 00.00 which is false by itself it should be around 00.09-00.19, it was off by 65% measuring thorium it showed nothing, this product is a piece of Chinese craftsmanship and should be taken off Amazon for its false readings and slow to zero reaction time, this is literally a child’s toy, I mean I hope you are not in a position where you actually need one of these because you would display ARS before your meter measures any levels of radiation. If I could I would give zero stars and I would like a full refund. Never again will I buy something this important for so cheap.

it's ok for this money

Es ideal para detectar radiación fuerte, sin embargo no funciona tanto con materiales que son pocos radiactivos, como el vidrio vaselina. En cuanto la entrega; fue puntual y venía en muy buen estado la caja y el contador, al igual que contiene todo lo que dice.
