## Description

GC-03 is a multifunctional radiation detector, a professional instrument for measuring nuclear radiation, mainly used in various occasions such as home, office, car, outdoor environment, etc. It uses a 2.4-inch high-definition color screen and supports real-time monitoring of nuclear radiation, electric field strength, magnetic field strength, etc. The meter supports three alarm modes: sound, vibration, and light.
Key Features
3-in-1 Radiation Detection: Detects electric fields, magnetic fields, and nuclear radiation — all in one device for comprehensive safety monitoring.
High-Precision Geiger Counter Tube: Equipped with J321/M4011 GM tube for precision detection, high sensitivity and low power consumption.
Wide Application Scenarios: Ideal for use around nuclear power plants, seafood, imported food, CT scans, microwaves, laptops, refrigerators, washing machines, and more.
Dynamic Curve Mode + 50 Alarm Records: Real-time radiation trend visualization with up to 50 stored alarm history records for traceable monitoring.
Triple Alarm Modes with Custom Thresholds: Get alerts via visual, audible, and vibration modes. Set custom alarm limits for different working conditions.
Wide Measurement Range: Measures dose equivalent rate from 0.00–10,000μSv/h (10mSv/h) and cumulative dose up to 500.0mSv , suitable for both daily and professional use.
Full Spectrum Ray Detection: Supports detection of γ, X, Hard β Rays radiation , covering various radiation types.
Smooth Rotary Knob Control: User-friendly rotary knob design makes switching functions quick and intuitive.
