Portable size: The small size of this tool makes it very convenient for daily use and can be carried around in a tool bag without taking up much storage space. Real-time dose (REAL): updated once per second, quickly displaying the real value at each moment, with the characteristics of large fluctuation and high consistency with the detection result of the sensor. The real-time value is automatically tested and displayed, and no operation is required after power on. (Unit: usv/h) Average dose (AVG): record the total dose received over a period of time, and convert it into an average display, which is characterized by small fluctuations, which is convenient for viewing the numerical environment background and low radiation environment . Press the M key to recalculate the average value (unit: usv/h) Accumulated dose (ACC): that is to add all the detected doses, the data will not be lost after shutdown, and the historical data will continue after restarting Accumulation, there will be a long-term cumulative sum value. You can clear the accumulated value by pressing the L and R buttons at the same time. (Unit: msv/h) Wide application: The nuclear radiation detector can be widely used in nuclear physics, environmental monitoring and industrial fields.
