Overview
Enviro Test Construct portable combustible gas detector are to quickly and accurately detect gas leaks or gas concentration exceeding the alarm limit. The main detection principles of gas detection are electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionization, etc. This is widely used in firefighting, emergency rescue, confined space, petroleum, chemical industry, metallurgy, refining, gas, storage, medicine, environmental protection, air treatment and other occasions.
