Features:

 Real-time measuring dose rate and accumulated dose of ambient radiation.

 Dose rate alarm threshold and dose alarm threshold can be set arbitrarily (continuously adjustable).

 It's available to check the start time of the present accumulated dose.

 It possesses statistical function, statistical time is between 00 to 99 hours, and can be set arbitrarily.

 It possesses both dose rate function and dose double alarm function.

 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 999Sv/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 has calendar clock function, even the clock is turned off, it can operate normally.

 It has data export function, configured with USB interface, which is easy to connect with computer, and is available to read, analyze and manage dose data by personal dose management system software.

 It is able to monitor battery level continuously, with prompt for low battery state.

 Chinese/English language menu, easy to switch.

 Simple, accurate and compact detector with user-friendly design, easy to operate.

 Dot-matrix LCD display, and its backlight is switchable.

 It is widely used in ionizing radiation environment such as home appliance radiation, irradiation processing enterprises, radiotherapy, nuclear laboratories, nuclear power plants, import and export commodity inspection, building materials, petrochemicals, geological surveys, steel and iron scraps, industrial non-destructive testing and other areas, so as to supervise the radiation dose that personal has taken and areas where needs to caution.
