Features:
Measure real-time dose rate and accumulated dose.
Dose rate alarm threshold and dose alarm threshold can be set arbitrarily (continuously adjustable).
Either sound alarm mode or flash alarm mode or any combination of them can satisfy various alarm needs.
It has alarm prompt function for sensor malfunction (Display screen shows “////GMBad”).
It has alarm prompt function for blocking when the radiation dose rate exceeds 10 mSv / h, (display shows 99.99Sv / h).
It has built-in memory, even if the power is off, the accumulated dose value, dose rate alarm threshold and dose alarm threshold data will not get lost.
It is able to monitor battery level continuously, with prompt for low battery state.
