Feature:1. Portable Size: The small size of this tool is very convenient for everyday use, you can carry it in your tool bag without taking up too much storage space.2. Real-time dose(REAL): Update once every second to quickly display the true value of each moment, characterized by large fluctuation and high consistence with sensors detection results. The real-time value is automatically tested and displayed without operation after boot. (Unit: usv/h)3. Mean dose(AVG): Record the total dose received over a period of time and convert it into the mean display, characterized by small fluctuation and convenience to check the background value of the environment and weak radiation environment. Press the M button to recalculate the mean value. (Unit: usv/h)4. Cumulative dose(ACC): That is, add all the detected doses, and the data will not be lost after shutting down, and historical data will continue to be accumulated after booting up again, and there will be a long-term cumulative sum value. You can press L button and R button simultaneously to clear cumulative value. (Unit: msv/h)5. Wide Applications: This nuclear radiation detector can be widely used in nuclear physics, environmental monitoring and industrial fields.Specification:This nuclear radiation detector can be widely used in nuclear physics, environmental monitoring and industrial fields. There are three detecting modes: real-time dose, mean dose and cumulative dose to meet your different needs.
