Chloromethane alarm is an imported sensor with high detection accuracy, stable performance, reliable quality, strong anti-poisoning and anti-interference ability. It has the national product certificate, national measurement certificate, explosion-proof certificate and so on.
This product is composed of chloromethane alarm controller and chloromethane alarm detector. The chloromethane alarm detector and chloromethane alarm controller are connected by shielded cable. The chloromethane alarm controller should be installed in non-explosion-proof places such as fire fighting center, fire fighting duty room and instrument room. The chloromethane alarm controller can control the unit at the same time and detect several detectors on a round trip. The gas concentration of each detection point is displayed independently. The host and detector are connected by bus system or wire-splitting system. It is convenient to install and distribute the network. It can centralize the control of multiple monitoring points. When the concentration of detected gas reaches or exceeds the predicted value in the environment. When the alarm is on duty, the chloromethane alarm immediately sends out sound and light alarm to remind users to take safety measures and drive the exhaust air, cut off and spray system to prevent explosion, fire and poisoning accidents, so as to ensure safe production.
