Gas detector GR31

JTO A new type of detector with a higher degree of protection. It replaces the older detectors GI31 designed for the ZONE 2 environment. It uses a sensor based on detection through infrared rays. The detector has a wide supply voltage range and includes current loop output 4-20 mA.

The areas of application are primarily areas with defined ZONE 2 environment or where there is a possibility of influencing the semiconductor sensor by other gases.
