GMC-320 digital Geiger Counter
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
an USB port for communication and external power supply/charging
of the internal rechargeable battery.
GMC-320 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 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
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.
