## Long description

The Fnirsi GC-03 WT is a professional-grade multifunctional ionizing radiation detector designed for precise monitoring of X-ray, gamma, and beta radiation levels. This advanced device combines nuclear radiation measurement with electric and magnetic field detection, providing a comprehensive solution for environmental safety. Equipped with a high-sensitivity energy-compensated Geiger-Müller tube, it ensures reliable performance and fast response times for both home users and professionals.
Advantages
This multifunctional detector offers significant versatility by integrating three measurement types into one compact device, effectively replacing the need for multiple separate tools. Its high-precision sensor allows for the detection of both natural background radiation and potential hazards with great accuracy. The inclusion of a dynamic curve mode and an alarm history log enables users to track radiation trends and review past events, while the triple alarm system—featuring sound, vibration, and visual alerts—ensures that users are notified immediately when thresholds are exceeded. Furthermore, the device is designed for ease of use, featuring a clear 2.4-inch color display and an intuitive rotary knob for navigation.
Suitable for
Monitoring background radiation levels in residential or work environments
Detecting radiation from household appliances and electronic equipment
Assessing electromagnetic field exposure from electrical installations
Educational purposes and scientific demonstrations
Industrial safety monitoring and personal radiation protection
This device may not be suitable for highly specialized laboratory research requiring certified calibration for specific isotopes or extreme environmental conditions outside the specified operating range.
