Ms400-S Versatile Gas Detector for Electrochemical, Infrared, and Pid-Based Detection in Firefighting, Rescue, and Occupational Health Scenarios
OVERVIEW
MS400-S Portable Multi-Gas Detector
The MS400-S is a portable multi-gas detection device designed for fast and reliable identification of gas leaks and hazardous concentrations. It supports up to four digital sensors within a single modular unit, each automatically recognized and easily replaceable via plug-and-play design. The detector utilizes a variety of sensing technologies including electrochemical, infrared (IR), catalytic combustion, thermal conductivity, and PID photoionization to accommodate different gas types and detection needs. Engineered for use in demanding environments, the MS400-S is widely applied in firefighting, emergency response, confined space entry, oil and gas industries, chemical processing, metallurgy, refining, warehousing, pharmaceuticals, environmental monitoring, air quality management, and more.
