JH-DREA combustible gas detector
The JH-DREA type point-type combustible gas detector with a measuring range of 0-100% LEL (hereinafter referred to as the detector) is a smart detector developed by our company that outputs a 4-20mA current signal and displays it in real time. This product has the characteristics of high stability, high accuracy and high intelligence.
The detector is suitable for the place where flammable gas exists, and displays the concentration value of flammable gas in real time. When the concentration of on-site flammable gas exceeds the set alarm value, the detector outputs an on-off signal, which can be linked to external equipment: such as sound and light alarm, exhaust ventilation, valve closing, etc.
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 "" and GB15322. 1-2003 "Part of the combustible gas detector: Point-type combustible gas detector with a measuring range of 0 to 100% LEL" was designed and passed the examination of the National Instrument Explosion-proof Inspection Station.
