FNIRSI GC-01 Product Manual:https://www.mediafire.com/file/
The FNIRSI GC-01 nuclear radiation detector uses a higher-precision Geiger-Miller counter.
Counter for detecting the intensity of ionizing radiation (beta particles, gamma rays and x-rays).
Use a gas tube or a small chamber as a probe.When the voltage applied to the probe reaches a certain range.Each time the ray is ionized in the tube to produce a pair of ions, it can be amplified to produce an electric pulse of the same size.And recorded by the connected electronic device.The number of rays per unit time thus measured.The alarm threshold measurement rate can be arbitrarily selected.














Appareil qui a l'air de bonne qualité.Pas de source radioactive pour tester.
Все було добре запаковано,але,не зрозумів чому не іде рахунок.4 фото.Все стало зрозуміло після розборки.5 фото.На жаль таке буває.
Very good quality item
Just to confirm what others have observed. Ordered from official FNIRSI manufacturer seller. Has version 1.8 firmware. Has J321/M4011 Geiger tube. Ordered 08/18/2025, received 08/24/2024. Sale price was US $33.14 (no additional tariff charged). This is the REAL FNIRSI GC-01, not the multitude of counterfeit ones also being sold on AliExpress. It is really a shame that FNIRSI and/or AliExpress cannot/or will take action against all these counterfeit GC-01's being advertised.
