Ⅰ. 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.
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.
Ⅲ. Technical Specifications
Cumulative dose: Hp (10): 0.0mSv~10Sv;
Dose rate: Hp (10): 0.1mSv/h~500mSv/h；
Alarm threshold setting
The cumulative dose alarm is continuously adjustable between 1μSv to 10Sv;
The dose rate alarm is continuously adjustable between 1μSv / h to 500mSv / h.
The sound and light alarms and LCD indications can be set for the out-of-limit of cumulative dose and dose rate, battery under-voltage, operating overtime or detector failure alarm, and a sound and light indication can be set for cumulative dose increment.
