Product Overview:

With the rapid development of industry, there are more and more occasions where humans come into contact with harmful gases, resulting in increasing harm to humans themselves. The repeated poisoning accidents have made people realize the importance of protecting human safety while developing industry. Therefore, various harmful gas alarm devices have gradually become essential protective equipment in industrial safety production.

Point type gas detector (hereinafter referred to as probe) is a new product developed by our company using advanced electrochemical sensors and years of experience in gas detection probe research and development. It can be widely used in metallurgy, petroleum, petrochemical, chemical, light industry, coking, municipal, gas, pharmaceutical, sewage treatment and many special industries and fields. It can detect various gases separately, such as flammable gases and more than ten toxic gases including O2, H2S, CO, HCN, NO2, SO2, NH3, HCL, CL2, H2, etc. The instrument adopts an intrinsic safety circuit design, with a 4-20mA standard signal two-wire system (three wire system for combustible gas) output, which can be transmitted over long distances and directly enter the DCS system. The probe has the characteristics of high sensitivity, rapid response, long service life, and short polarization time, and is at the leading level of similar products in China.
