Wire gas detection transmitter is a kind of our companys products whichcan continuously detectpoisonous and harmful, inflammable and explosive gas concentration in the working environment . This transmitterdetects gas concentration in the form of natural diffusion Detector to detect gas concentration in the form of natural diffusion, using imported sensors with good sensitivity and good repeatability; Our Wire gas detection transmitteradopts the embedded microcontroller control technology, high reliability. Its shell is made of aluminum material with high strength, heat resistance and corrosion resistance. Our product has widely used in detecting toxic and harmful gas or oxygen content detection in metallurgical industry, power plants, chemical industry, mine, tunnel, tunnels, underground pipeline and other places, effectively prevent the happening of the accident.
