Assembled DIY Geiger Counter Kit Module Nuclear Radiation Detector with LCD Display (Standard)

This is a kind of fine quality nuclear radiation detect module, Plug it and you can directly measured nuclear radiation. For the detection of 20mR/h-120mR/h of gamma rays and 100-1800 off variables/points of the soft beta ray. You can have a try.

Features:
For the detection of 20mR/h-120mR/h of gamma rays and 100-1800 off variables/points of the soft beta ray.
Equipped with sound and light alarm.
Interrupt the output interface, through this interface can be connected to the microcontroller and then displayed on the LCD display.
Supports most of the Geiger tube: M4011, STS-5, SBM20, J305, etc. (the 330-600V operating voltage of the Geiger tube can be supported).
Support the computer (PC) data acquisition, Matlab analysis and processing.
