FNIRSI GC-02 Nuclear Radiation Detector with Geiger-Müller Tube, Alpha/Beta/Gamma/X-Ray, 2.8 inch TFT, USB-C

The FNIRSI GC-02 is a professional-grade nuclear radiation detector designed for accurate measurement of alpha (α), beta (β), gamma (γ), and X-ray radiation. Featuring an energy-compensated Geiger-Müller tube sensor, this device provides reliable dose rate and cumulative dose readings with a wide measurement range. Its 2.8-inch TFT color screen displays real-time data in multiple units, while adjustable alarm thresholds with sound, vibration, and visual alerts ensure user safety. Powered by a built-in 1100mAh lithium battery with USB Type-C charging, the GC-02 is ideal for environmental monitoring, industrial safety, and educational purposes.

Advantages

High sensitivity (80 CPM/µSv/h for Co-60) and low relative intrinsic error (≤±10% at 1 mSv/h) ensure precise measurements. The device supports multiple measurement units (µSv/h, µGy/h, mR/h, cps, cpm) and offers a fast response time of less than 10 seconds. Its compact, portable design with a long battery life of up to 20 hours makes it suitable for field use.
