The Guardian range of infrared gas monitors offer high levels of performance, repeatability and reliability in the detection, measurement and direct control of target gases. Guardian monitors are also simple to install, requiring only connection to a 110V or 220V AC electricity supply.

Monitors to be located up to 30M distance from the sampling point.

Guardians feature an internal audible alarm, 2 infinately variable alarm threshold settings, LCD display of gas concentration, gas flow and fault condition alarms. Integral alarm relays can be used for direct control of processes.

The 'fail to safety' attributes of our infrared gas monitors offer distict safety advantages over other technologies.
