Product Description

GA-50 Gas Detector 

GA-50 fixed gas detector adopts advanced catalytic gas sensor or electrochemical sensor. It is used to detect the concentration of flammable gases or other toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value. The controller will give an audible and visual alarm, promptly remind people to take safety measures to prevent the occurrence of explosions and poisoning incidents.



Application

GA-50 can be used to detect gas in petroleum industry, refinery, chemical plant, LPG station, painting plant, fire protection, municipal industry and other places with gas exists.

Feature
•      International brand micro process sensor
•      4~20mA analog output, RS485 output
•      Can be integrated with all kinds of control system, alarms, PLC panel, etc.
•      Explosion proof grade: ExdIICT6 Gb
•      With self-calibration & zero-calibration function. With temperature compensation. 
       More accurate and reliable detection.
