Product description
The point type oxygen O2 detector is applicable to the concentration of oxygen in the ambient air detection, are widely used in metallurgy, power plant, chemical, mine, tunnel,underground pipelines and other places, effective prevention of hypoxia and oxygen poisoning. It is a new type of gas leak detection instrument produced by our company. Its outstanding feature is the use of high-performance imported catalytic combustion, electrochemical, infrared dual-beam gas sensors, combined with sophisticated SMD technology, and it has a good It has the advantages of repeatability and resistance to humidity and temperature interference, long service life, and convenient operation. It is suitable for gas leakage concentration detection in various industrial environments.

TCB4 series point-type gas detectors can convert the leakage gas concentration signal in the air into electrical signals and output remote transmission. It adopts two/three-wire system, 485 bus, switch value and other signal structures. The monitoring instrument or controller host is kept away from the scene to view the detection results .
