FJ1210(φ50) Portable α β Surface Contamination Meter, Detect Alpha Beta Gamma X‑ray, Flat Dual‑flashing Detector Radiation Contamination Monitor
FJ1210(φ50) Portable α β Surface Contamination Meter, Detect Alpha Beta Gamma X‑ray, Flat Dual‑flashing Detector Radiation Contamination Monitor
【Product Introduction】
The FJ1210 (φ50) type radioactive detector is a portable radiation measurement instrument, mainly used for measuring surface α and β radioactive contamination and X and γ radiation dose rates. The instrument is equipped with a flat dual-flashing detector. It uses a high-speed, low-power microprocessor as the data processing unit, a large-screen, backlit graphic dot matrix LCD as the display interface, and a film keypad for operation. The operation is simple and convenient. Users can also set parameters such as measurement time, alarm threshold, nuclide efficiency, etc. Meanwhile, the instrument has functions of over-threshold alarm, under-voltage alarm, counting fault alarm, and high-voltage fault alarm.
