FNIRSI® GC-03 Multifunctional Radiation Detector

FNIRSI GC-03

Excellent dosimeter and EMF detector. My only comment would be if it had a screen timeout function but then remained on in the background. It is quite battery hungry but detection is good. I tested it with a Thorium gas mantle which is a source of Thorium-232 and low beta emission and it showed a good reading. Having a Geiger Muller tube it is far superior to the cheaper alternatives.

Good afternoon. I've been using the device for 2 weeks. What I would like to change or add: 1. A sleep mode for the screen to extend its lifespan. 2. The ability to adjust the schedule time (1-60 minutes, the total time since the device was turned on). 3. The accumulated dose should be reset instead of being reset automatically after the device is turned off. 4. The Alarm record does not record the time, only the date of the incident.

Satisfaction

Hello. My Fnirsi GC-03 device has arrived. It's very easy and comfortable to use. The measurement results have also given me peace of mind in my current environment. The power switch on the side was activated by contact when I put the device back in its case, and it remained on in the case for a day, draining the battery. I was worried it might be damaged from being left on for so long, but I didn't experience any problems. Thank you for this opportunity to return. Have a good day.
