Fields of application
The gas analyser MGA 23 can be used in emission measuring facilities as well as in systems of process and analysis measuring technology. It is approved for the use according to 13 th BImSchV and TI air.

By means of the gas analyser MGA 23 up to 4 gas components can be measured at the same time: maximum 3 infrared-active gases as e.g. CO (carbon monoxide), CO2 (carbon dioxide), NO (nitrogen oxide), SO2 (sulphur dioxide), CH4 (methane) as well as O2 (oxygen) with an electrochemical measuring cell.

Smallest TÜV-approved and permitted measuring ranges:

1- and 2-component-analyser
CO2: 0 to 150 mg/m³
NO2: 0 to 250 mg/m³
SO2: 0 to 400 mg/m³
3-component-analyser
CO2: 0 to 250 mg/m³
NO2: 0 to 400 mg/m³
SO2: 0 to 400 mg/m³
All higher measuring ranges are also allowed.
For use in non-potentially explosive atmospheres!
