Overview
The GQ GMC-300E Plus digital Geiger Muller Counter is designed to be a portable and
convenient device. It can be used as industrial, commercial maintenance, research,
evaluation, simulation and other analytical or scientific applications in areas such as
industrial plants, public utilities, hospitals, universities, laboratories, and electronic repair
shops. 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, 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 an USB port, utilized for communication and external power
supply/charging of the internal rechargeable Li-ion battery.
The GQ GMC-300E Plus internal rechargeable battery can be charged with a standard USB
wall adapter or with the car USB power adapter. 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 also has a real time clock on board for time related data logging purposes.
The USB port communicates with the
GQ GMC-300E Plus Soft Geiger Counter
software
and the
GQ Geiger Counter Data Viewer
software.
The
GQ GMC-300E Plus Soft Geiger Counter
software’s appearance is an exact copy of
the GMC-300E Plus hardware human interface. You can download it for free and experience
the GMC-300E Plus 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 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.
