4 Channel Gas Detector Controller-GMA-22M

4 Channel Gas Detector Controller-GMA-22M

We developed the GMA22-M specifically for gas measurement in this application. Up to four transmitters and relay modules can be connected to the controller.

A display showing measured values, integrated visual and audible alarms, and four internal relays for additional safety measures round off the extensive features of the GMA22-M. Gases need to be monitored in many processes – regardless of the plant size. Even in smaller applications, a gas warning system is indispensable.
