FNIRSI GC-02

One of the key advantages of this model is its high-precision Geiger–Müller (GM) tube, which enables real-time monitoring of ionizing radiation in a compact handheld device. The FNIRSI GC-02 detects gamma (γ), beta (β), and X-ray radiation, displays instantaneous, average, maximum, and cumulative dose values, supports configurable audible and visual alarms, and stores measurement records. It is ideal for monitoring environmental radiation, inspecting building materials, scrap metal, minerals, medical equipment, and other objects for radioactive contamination.
