FNIRSI GC-03 BK Multifunctional Ionizing Radiation Detector

The FNIRSI GC-03 BK is a professional multifunctional ionizing radiation detector designed for accurate measurement of alpha, beta, gamma, and X-ray radiation. Featuring a compensated Geiger-Müller tube sensor and a 2.8-inch TFT color display, this device provides real-time dose rate and cumulative dose monitoring with adjustable alarm thresholds. Ideal for safety professionals, researchers, and hobbyists, it offers reliable performance in a compact, portable design.

Advantages

High sensitivity and accuracy with a relative intrinsic error of ≤±10% (for 137Cs at 1 mSv/h). The built-in 1200mAh rechargeable lithium battery supports up to 4-6 hours of continuous operation, and the USB Type-C charging interface ensures convenient power management. Multiple alarm modes (sound, vibration, visual) and adjustable thresholds enhance safety. The device stores historical data for review and supports multiple units of measurement (µSv/h, µGy/h, mR/h, cps, cpm for dose rate; µSv, mSv for cumulative dose).
