The GQ GMC-300E Plus is a portable Geiger Counter with built in audible and visual signals for the level of radiation detected. It can be used for radiation detection and monitoring both indoor and outdoor, as well as in other similar environments. It features automatic data recording, and can continually monitor the radiation and log the data each second into internal memory. When connected to a PC, software can download the radiation history data to the computer and the user is able to analyze those data later (basic logging software download available for free).

The device is equipped with an USB port, utilized for communication and external power supply/charging of the internal rechargeable NiMH battery. The GQ GMC-300E Plus internal rechargeable battery can be charged with the supplied wall adapter or with the car adapter for the cigarette lighter. Using the adapters, continuous data monitoring is possible. Using either power adapter you will not have to worry about the batteries charge condition or any data loss.

The main board has a real time clock on board for time related data logging purposes. The USB port communicates with the GQ GMC-300E Soft Geiger Counter software and the GQ Geiger Counter Data Viewer software. The GQ Geiger Counter Data Viewer software can download the time stamped radiation (history) data from the unit and save it on a computer for future reference and analysis.
