Product specifications:

Application of imported extensive Halogen-quenched Geiger-Mueller tube: Mica window, area density 1.5-2.0 mg/cm², effective diameter 1.75″ (45 mm);
High brightness 2.4″ true color touch screen: easy to operate and simultaneously display dose rate, cumulative dose, ambient temperature, radiation risk, radiation peak and display real-time clock to provide time-cutting protection for the data;
The measuring unit is automatically adjusted with the change of radiation energy without manual intervention;
Testing a variety of rays: α、β、γ and X;
Average cycle: the displayed readings are updated every second. In low background value detection, the update rate is the moving average of the previous 30 seconds. The time period will decrease as the radiation value increases;
Sleep function: when the battery voltage is too low, the instrument enters the sleep state to protect the data and equipment, and automatically restores to work after charging;
Excellent nuclear radiation detection algorithm: high range, high precision, and high sensitivity;
Three alarm modes: sound, light flash, and vibration, can be arbitrarily combined and set;
Green, low power consumption, 2600 rechargeable lithium batteries.
