Features 1、1. This is a small high-sensitivity radiation dose alarm instrument, mainly used to monitor X, B rays and Y rays. It has the characteristics of high sensitivity and accurate measurement. 2、2. The microprocessor with powerful performance is selected, and it is equipped with a TFT2.0 color screen, which makes the operation simple and user-friendly, and has strong anti-interference ability. 3、3. The two alarm methods of sound and flash can be combined arbitrarily, and the alarm threshold can be set arbitrarily. When the alarm threshold is reached, an alarm will be issued to remind the staff to pay attention to safety. 4、4. You can view the start time of the current dose accumulation. With timing measurement function, it can be set arbitrarily between 00-999 hours. The history record information of the last 10 measurements can be saved. 5、5. With calendar clock function, the clock can be guaranteed to run normally after shutdown. The battery level is continuously monitored with a battery level icon. With sensor fault prompt function. (Display shows "Device is damaged") 6、6. When the recorder is turned on and the screen is off, the monitor will automatically alarm if it detects that the radiation dose exceeds the set alarm value. It will automatically jump to the radiation measurement page.
