MS104K-L Single Gas Detector
All cases require portable rapid detection of gas concentrations such as petroleum, chemical, pharmaceutical, environmental protection, combustion gas distribution, warehousing, flue gas analysis, air management, etc.
The main functions of the MS104K-L portable gas detector are to The main functions of the MS104K-L portable gas detector are to quickly and accurately detect gas leaks or gas concentrations exceeding the alarm limit. The main detection principles of gas detection are: electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionisation, etc. The MS104K-L is widely used in firefighting, emergency rescue, confined space, petroleum, chemical industry, metallurgy, refining, gas, storage, medicine, environmental protection, air treatment and other occasions.
