FNIRSI® GC-01 Nuclear Radiation Detector
Product Description
The FNIRSI GC-01 Nuclear Radiation Detector is a portable radiation measuring instrument designed to detect ionizing radiation from Gamma (γ), X-ray, and Beta (β) rays. It uses an energy-compensated Geiger-Müller (GM) tube to detect radiation and measure the radiation dose equivalent rate and cumulative dose equivalent.
The GC-01 provides real-time radiation monitoring through a high-definition LCD screen, displaying current dose rate, average and maximum values, cumulative dose information, and configurable alarm thresholds. Its measurement units can be switched between μSv/h, μGy/h, mR/h, CPS, and CPM to suit different measurement preferences.
For monitoring and notification, the device supports three alarm modes: indicator light, vibration, and sound. Users can configure current dose-rate and cumulative-dose alarm thresholds, while the built-in clock and data retention function help maintain measurement records and operating information.
With its compact handheld design, rechargeable 1100mAh lithium battery, and selectable English and Chinese interface, the FNIRSI GC-01 is suitable for radiation monitoring and inspection in industrial, laboratory, environmental, and educational applications.
