TCB4 series type gas detector is a new type of gas leak detection instrument produced by our company, its prominent feature is the use of imported high performance catalytic combustion, electrochemistry, dual beam infrared gas sensor, combined with sophisticated SMD technology, has good repeatability and wet temperature interference, using the advantages of long service life, convenient operation etc.. It is suitable for detection of gas leakage concentration in various industrial environments.
The TCB4 series point gas detector can transform the leak gas concentration signal in the air into electrical signal output and remote transmission. The signal structure of two / three wire system, 485 bus and switch volume is used to observe the detection result from the monitoring instrument or controller host away from the scene
The product is suitable for oil refineries, chemical plants, gas stations, gas boiler room, refueling stations, paint room, pharmacy, iron smelting using inflammable and explosive materials, toxic and hazardous industrial site gas safety detection and alarm.
