Handheld Single Combustible Gas Detector %VOL/%LEL/mg/m3/ppm/ppb
Multiple Units Available
OVERVIEW
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.
