Radiation Detector

R-EGD Radiation Survey Meter



R-EGD radiation survey meter  is a kind of special device used to monitor X and gamma radiation dose rate of various radioactive workplace.The device has a quite large dose rate measuring range and it increases the function of the cumulative dose,which makes the device more extensive uses,be well received by the majority of users,especially health supervision department users.

It uses the latest Cortex-M3 CPU core, the detector using a Geiger counter tube.The device has a wide measuring range as well as good energy response characteristics due to the detector through effective energy compensation.




1.  High sensitivity,large measuring range
2. High EER CPU, color LCD display, adjustable backlight
3. Chinese and English display, easy to operate
4.  Dose and dose rate can be measured
5.  Alarm: Dose rate threshold alarm , dose rate overload alarm,detector fault alarm, battery under-voltage alarm
