CE Certified 4 in 1 Gas Detector for CH4, CO, O2, H2S
Besides our own gas detectors, we have customized many kinds of gas detectors for our customers from all over the world. We can customize plastic enclosure, pcb and the whole gas detector according to customer's requirements.
Application:
it’s used in industrial or mining applications, including underground Coal Mine, petrochemical, metallurgical, chemical, municipal gas, and other places at the scene detection.
