Analyzer based on the measuring of non dispersive infrared absorption (NDIR) for CH4 and CO2 gas. The enclosure is a solid 19" rack mounting 2 module box. The measuring are displayed on 7 segments led displays that also have two configurable alarms for each measure. The alarms are displayed with led on the front panel and put on 4 digital potential free contacts.

On the front panel are mounted two flow meter (one for each measure) to control and set up the effective gas passage in the analysis chamber.
