. Product Introduction

This dosimeter is mainly used to monitor the individual cumulative dose equivalent and dose equivalent rate caused by X and γ radiations, issuing a sound and light alarm when the cumulative dose or dose equivalent rate is over the alarm setpoint. The dosimeter is controlled by a low-power singlechip, with the real-time display of measured value, sound and light alarms for over limitations, the EEPROM data storage, alarm threshold parameter settings, the detector failure alarm, and the battery under-voltage detection and other functions. Measured data can be stored without any loss in case of power failure.

.Main Features

l  Small size, wide range, and high reliability

l  Real-time alarm display; data can be stored without any loss in case of power failure.

l  USB port communication is provided, convenient for computer standardized management

l   Built-in rechargeable battery, easy to use.
