FNIRSI GC-03 BK Multifunctional Ionizing Radiation Detector

The FNIRSI GC-03 BK is a multifunctional ionizing radiation detector that combines a Geiger counter, electric field meter, and magnetic field meter in one compact device. Featuring an energy-compensated Geiger-Müller tube, it measures radiation from 0.01 to 10,000 μSv/h with high sensitivity (80 CPM/μSv). The large 2.4-inch color TFT display offers three operating modes: Quick View, Professional, and Curve mode for real-time trend analysis. A triple alarm system (audible, vibration, visual LED) ensures you never miss a warning, and the device logs up to 50 alarm events. With its compact size (138×63×32 mm) and lightweight design (141 g), it's perfect for home users and professionals alike.
