Geiger Counter




The GQ GMC-320 digital Geiger Counter is designed to be portable and convenient. The device comes with built in audible and visual signals for the level of radiation detected. It can be used for radiation detection and monitoring both indoors and outdoors.

It features automatic data recording, with the ability to log the data each second into it's built-in 1 MB flash memory. It can continually monitor and the history is searchable. When connected to a PC, software can download the radiation history data to the computer so the user can analyze the data later.

The device is equipped with a USB port for communication and external power supply/charging of the internal rechargeable battery. Using the USB cable, continuous data monitoring is possible. Doing this you will not have to worry about the batteries charge condition or any data loss.

The main board also has a real time clock for time related data logging purposes.

The USB port communicates with the GQ GMC-320 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 references and analysis.

The GQ data viewer software also can be used as realtime data monitor. User is able to save the realtime data into Excel .csv, text format, HTML file format and other formats.
