Online type gas detector can be used in 24 hours continuous online monitoring of field gas concentration, 1.7-inch high-definition color screen will be used for the display of the field concentration, with field sound & light alarm (optional) when exceeding the standard, and remote signal transmission. The gas sensors of internationally known brands are adopted, and the main detection principles include: the gas sensors under the principle of electrochemical, infrared, catalytic combustion, thermal conductivity,PID photoionization, and so on. Is suitable for detecting the concentrations of gases in the atmosphere environment in the pipeline or confined space; and the purity of the gas leakage and various high concentration single gases with the background gas as nitrogen gas or oxygen gas. The types for detection are more than 500 types. Strong, durable and explosionproof shell is suitable for the use at a variety of hazardous places and harsh industrial environments, is widely used in the industries such as petroleum, chemical, metallurgy,refining,gas transmission and distribution, biochemical and pharmaceutical, and so on.
