MS104K Portable 4-in-1 Multi Diffusion Type Gas Detector
The MS104K-M four-in-one gas detector is essential for swiftly and accurately identifying gas leaks, sounding alarms when gas levels exceed safe limits. Utilizing a range of detection technologies—including electrochemical sensors, infrared analysis, catalytic combustion, thermal conductivity, and photoionization detection (PID)—this tool is reliable in various settings. It’s widely used in fields like firefighting, emergency response, confined space monitoring, petroleum and chemical sectors, coal mining, metallurgy, refining, gas handling, storage, medical applications, environmental sustainability, and air quality management.
