GQ GMC-320S Digital Nuclear Radiation Detector Monitor Meter Geiger Counter Radiation Dosimeter

Lo compré como regalo a mi esposa que es física y que está interesada en medir niveles de radiación anormales en México. Hasta ahora solo encontramos un lugar anormal en casa que marca 45. Estaremos investigando más debido al incidente de Cobalto de Cd Juarez y las varillas de acero contaminadas.

I purchased this gadget for our "bug out" bag, just in case of whatever in todays world. Upon initial charging I tinkered with it experimenting on different household devices and found it really works great, picking up readings from cell phones and certain appliances. I attached the chart to the gauge and am confident that this would alert us if any radiation instances come about, in order to take proper shelter. The unit is small and easy to carry or store, plus very affordable for our retirement budgets.

Works as described och quality seems ok

Easy to use. No way for a non-expert to know precisely how accurate it is, but I assume it's doing a reasonable job.

The media could not be loaded.  Not really much more expensive than many Chinese geiger counters this device is clearly the better choice. Better stability and none of the quircks/bugs/errors often found in inexpensive chinese geigers. Only thing to wish for is it was powered on two AA - but that is also a metter of preference. At least the 14500 LiIon cell is easily replaceable and it has option in setting to be powered by lithium tionyl (more correctly non rechargeable so it doesn't charge the tionyl when connected to USB). So it's possible to have a few li-thionyl for an emergency in the even the LiIon is dead - would just be more convinient if it was regular 1,2/1,5 V AA.
