Overview
The.GQ GMC-320 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 GQ GMC-320 Plus installed a high contrast black/white LCD
module, one front LED indicator and one analog data port. The analog data port can be
connected to any third party device application as data input.
The device is equipped with an USB port, utilized for communication and external power
supply/charging of the internal rechargeable Li-Ion 3.6V/3.7V battery.
The GQ GMC-320 Plus internal rechargeable battery can be charged with a standard wall
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-320 Plus Soft Geiger Counter
software
and the
GQ Geiger Counter Data Viewer
software.
The
GQ GMC-320 Plus Soft Geiger Counter
software’s appearance is an exact copy of the
GMC-320 hardware human interface. You can download it for free and experience the GMC-
320 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.
