GMI Geiger Counter InterfaceThe GMI contains a high voltage power supply, and interface to connect to a computer. You can connect the geiger counter tube of your choice to the BNC jack on the front of the unit, and select the appropriate operating voltage using the switch. Voltages from 450 to 1000 volts can be selected, in approximately 50 volt increments. A built in 10M ohm dropping resistor allows use with virtually any geiger mueller tube made. It does not work with scintillator probes.
Two versions of the GMI are available. One includes a USB adapter and plugs in to a USB port on your computer (Windows, Macintosh or Linux), and includes a 6 ft long USB cable. The other version plugs into a standard RS-232 serial port on your computer, and comes with a cable for the standard 9 pin PC serial port.
Since the GMI is self powered by the computer's serial port, no batteries or external power adapters are needed! You can operate them anywhere you can take your computer or laptop!
The GMI can also be connected to a microcontroller, or other embedded computer system for OEM use. Please feel free to contact us with any questions you may have.
The RS-232 version of the GMI is just $129, and the USB version is $179.
Included with your GMI is a copy of our Rad software for reading and storing data, as well as creating graphs and analyzing trends.
