Features:

 With high detection sensitivity, especially for environmental radioactivity  monitoring to detect traces of nuclear radiation.

 Configured TFT 2.0 color screen, real-time display of instantaneous value, average value, accumulated value and so on.

 The detector is used to measure X, γ and β rays radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides.

 The dose rate is measured in real time and the cumulative dose is recorded at the same time, and has a calibration function.

 With the combination of two alarm methods: sound and flash, while the dose rate alarm thresholds and metering alarm thresholds can be set at will (continuously adjustable).

 Timed measurements to set the starts-delay time to 00-99h and the measurement time to 00-999h. The device starts counting down, when the starts delay countdown is zeroed, the instantaneous value average and the accumulated time accumulated dose are zeroed at the same time. 

 The device also starts to count the radiation dose and the cumulative dose rate. At the end of the measurement time countdown the device automatically stores the interval measurement data. The measured data can be found in the history.

 Historical information of the last 10 measurements can be saved.. With calendar clock function, the clock can be kept running normally after the power is switched off, support year-month-day date setting and hour-minute-second setting.

 Continuous battery level monitoring with battery level icon.

 Multifunctional design, with Chinese and English language switch function, the operation language can be selected, which is suitable for different people. Measurement units switchable function.Sensors failure indication (display shows "device damaged").

 When the logger is switched on and off, the monitor will automatically alarm if the radiation dose is detected above the set alarm value. It will automatically jump to the radiation measurement page.

 Data deletion: Click on the Data Delete screen to access this screen to delete the current data and to delete the historical data. Current data deletion removes the average value and accumulated time from the radiation measurement page, while historical data deletion removes all data from the history.
