When it comes to measuring CO2 in safety critical situations such as brewing, refineries, nuclear, distilleries, bottling plants and landfill sites then the CO2 Multi Monitor from GMI is the ideal instrument.

It’s a fixed gas detection system with up to 8 sample inputs, designed specifically to monitor CO2 in the range 0 to 5% using long life and reliable infra-red technology.

Set-up and calibration are straightforward and easy using the Active-8-or hand held unit. A digital LCD and several LED indicators display system status. The system can be linked to alarms and other equipment within the facility via relays or analogue outputs.
