Single gas detector

Single gas detector is mainly used to quickly and accurately detect gas leakage or gas concentration exceeding the alarm. The main detection principles of gas detection are: electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoionization and so on. It is widely used in fire fighting, emergency rescue, confined space, petroleum, chemical industry, metallurgy, refining, gas, storage, medicine, environmental protection, air management and other occasions.
