Nuclear radiation detector Geiger counter X γ β-rays with real-time mean cumulative dose modes.
Screen is easy to read with good information & has an internal Geiger–Müller tube with sound alarm.
No batteries are included.
Real-time dose: (update once every second to quickly display the true value of each moment, characterized by large fluctuation & high consistency with sensor detection results. The real-time value is automatically tested & displayed without operation after boot. (Unit: usv/h)
Mean dose (AVG): Records the total dose received over a period of time & converts it into the mean display, characterized by small fluctuation to check the background value of the environment and weak radiation environment. Press the M button to recalculate the mean value. (Unit: usv/h)
Cumulative dose (ACC): adds all the detected doses, & the data will not be lost after shutting down, historical data will continue to be accumulated after booting up again, & 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)
