Toxic Gases
The GMI Transmitter sensors use proven electrochemical sensor principles to detect and monitor for a selection of toxic gases in the parts per million (ppm) range and % volume oxygen.  They are designed for use in non-hazardous area applications such as car park monitoring systems.
Gas sensors:  CO, VOC, SO2, Cl2, NO2, NH3, NO, Freon, H2S & O2.


CO2 Gas
The GMI Transmitter sensors use proven infra-red detection principles to detect and monitor for carbon dioxide gas.

There are two standard ranges available:  0-5% Volume CO2 and 0-100% Volume CO2.

They are designed for use in non-hazardous area applications such as brewing, landfill/biogas, refrigeration.

The GMI Transmitter Sensors operate on a 3/4 wire connection and provide a linear, calibrated 4-20 mA output to allow connections to our range of fixed control panels or, alternatively, direct to existing PLC, DCS or external control systems.

The sensor and the amplifier electronics are housed in a sturdy mild steel enclosure which has built-in external mounting lugs to allow ease of fitting.  The amplifier PCB has built in Zero and Span potentiometers to allow a simple and reliable calibration procedure.
