Gas analyser 

The robecco gas analyses RGA-CGM5 serves the continuous gas measurement e.g. CO, CO2 SO2, NO, O2. It is universally applicable for operational-, exhaust-, raw gas and process measurement.

Three different measuring methods can be selected depending on the measuring gas: Infrared absorption / electrochemical cell / paramagnetic measurement method.

The principle of infrared absorption allows the simultaneous measurement of up to five infrared gas components.
