FNIRSI GC-02 Geiger Counter Nuclear Radiation Detector Personal Dosimeter X-ray Y-ray Radioactivity Tester Marble Detector

FNIRSI GC-02 is a slim pocket-sized nuclear radiation dosimeter equipped with energy-compensated Geiger-Müller tube. It detects ionizing radiation including β, γ and X-rays, measuring real-time dose rate and cumulative radiation dose. The 1.5-inch IPS color screen displays real-time, average, maximum and cumulative radiation data, with visual trend graph. Users can customize radiation alarm thresholds with sound and light dual alert modes. Multiple dose units are switchable: μSv/h, μGy/h, mR/h, CPS, CPM. It supports multi-language interface, auto power-off and sleep mode. Built-in 850mAh rechargeable lithium battery with Type-C charging, continuous working time up to 6 hours. Widely used for marble inspection, medical radiation monitoring, ore testing, household safety screening and personal radiation protection.
