Some pictures here may be taken from a GMC-300 model, but GMC-300E Plus has the same features on it.

It is designed to be a portable and convenient device. 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 indoor and outdoor, as well as in other similar environments. It features automatic data recording. It can continually monitor the radiation and log the data each second into internal memory. When connected to a PC, the software can download the radiation history data to the computer and the user is able to analyze those data later.

The device is equipped with a 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 a wall adapter or with a car adapter for the cigarette lighter. If 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 mainboard also has a real-time clock on board for time-related data logging purposes.

The USB port communicates with the GQ GMC-300 Soft Geiger Counter software and the GQ Geiger Counter Data Viewer software.

The GQ GMC-300 Soft Geiger Counter software’s appearance is an exact copy of the GMC-300 hardware human interface. You can download it for free and experience the GMC-300 user interface before you purchase the real hardware.

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.

For professional data logging of radiation data, the GQ Geiger Counter Data Viewer(Logger) may be downloaded for free. An even more advanced version, the GQ Geiger Counter Data Logger PRO software may be purchased at low cost from GQ Electronics LLC.

The GQ data viewer software also can be used as a real-time data monitor. the user is able to save the real-time data into Excel .csv text format, HTML file format etc.

GQ GMC-300 provides open GQ RFC1201 communication protocol for easier system integration. See the software download section for a detailed protocol.
