IGM-13 fixed optical gas detector
The gas detector is designed for automatic, continuous measurement of the concentration of flammable hydrocarbon gases or carbon dioxide in the surrounding atmosphere. The calibration of explosive gas is produced with samples of methane, propane or hexane. The gas analyzer is designed for permanent installation.
Explosion-hazard areas and areas near external processing units, with possible formation of explosive mixtures of gases and vapors with the air according to GOST R IEC 60079-14-2008 and marking 1Exd [ib] IIC T4 Gb.
The gas analyzer is performed in a metal case with a transparent window for indication elements. In the case there are cable glands, cover to access the terminals of external switching and a module an optical sensor. Housing material is aluminum alloy (possible option: stainless steel).
