Carbon dioxide alarm professional manufacturers provide, using foreign imported sensors, high detection accuracy, stable performance, reliable quality, anti-poisoning, anti-interference ability and other characteristics, with the product certificate issued by the state, national measurement certificate, explosion-proof certificate, etc. Carbon dioxide alarm This product is composed of carbon dioxide alarm controller and carbon dioxide detector. Carbon dioxide detector and carbon dioxide controller are connected by three core signal lines. Carbon dioxide alarm controller should be installed in fire control center, fire duty room, instrument room and other non-explosion-proof places where people are on duty. Carbon dioxide controller can control unit at the same time and detect several detectors. Gas concentration of each detection point can be displayed independently. Host computer and detector are connected by bus system or branch line system. When the concentration of carbon dioxide gas in the environment reaches or exceeds the preset alarm value, the carbon dioxide alarm will immediately send out sound and light alarm to remind users to take safety measures, and drive the exhaust, cut off and spray system to prevent explosion, fire and poisoning. Accidents, thus ensuring safe production.
Products are sold to Shandong, Jiangsu, Henan, Zhejiang, Liaoning, Tianjin, Dalian, Xinjiang, Anhui, Fujian, Hubei, Hunan, Chongqing, Yunnan, Ningxia and other parts of the country.
