CGD-ZK point-type combustible gas detector (hereinafter referred to as the detector) with a measuring range of 0-100% LEL is an intelligent detector developed by our company that outputs RS485 digital signals. This product has the characteristics of high stability, high accuracy and high intelligence.
The detector is suitable for the place where flammable gas exists. When the concentration of on-site flammable gas exceeds the set alarm value, external equipment can be linked: such as sound and light alarm.
The detector is in accordance with the current national standards GB3836.1-2010 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", GB3836.2-2010 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion-proof Type" d "" GB15322.1-2003 "Flammable gas detectors Part 1: Point-type combustible gas detectors with a measuring range of 0 to 100% LEL" was designed and passed the examination of the national-level instrument explosion-proof safety inspection agency.
