Introduction
This article is not a full review. It is just a cursory evaluation.
Several weeks ago, I ordered a Multifunction Nuclear Radiation Detector from a eBay seller who imports these units from China. FNIRSI also sells several other electronic test equipment units, one of which I bought was the multi-function oscilloscope hoping that I could use it on the bench as well as for portable operations. Alas, I didn’t like the unit because the probe connections for the oscilloscope don’t fit well into the connector (BNC type) on the top of the case and because of that issue I broke off the connector for one of the two channels and when I disassembled the unit it effectively destroyed the outer lining for the case. I contacted the company but never got any reply from them or the seller I bought it from. I was able to repair the unit and make it operational, and it is not as good as advertised as far as sensitivity is concerned. It is just a glorified DMM. In that regard, it is good. So up front, just beware that if you buy any items from the FINRSI brand you’re on your own for user support. I am under no illusion that this unit will be any different in that respect. Caveat emptor.Continue reading“FNIRSI GC-03 Radiation Detector: An Evaluation, by Mike in Alaska”
