Handheld Single Combustible Gas Detector %VOL/%LEL/mg/m3/ppm/ppb Multiple Units Available
The MS104K-L portable gas detector is designed to rapidly and precisely detect gas leaks or concentrations that exceed the alarm threshold. Abbreviations for technical terms will be clarified upon first-use. The gas detection instruments utilize various detection principles, including electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionization, among others. The MS104K-L is commonly utilized in firefighting, emergency rescue, confined spaces, petroleum, chemical industries, metallurgy, refining, gas, storage, medicine, environmental protection, air treatment, and other settings.
