MS400 Portable N2 Detector

MS400 series portable gas detector is designed for rapid and accurate detection of multiple gas concentrations, along with environmental temperature and humidity measurement. When readings exceed preset limits, the device immediately triggers alarms. Featuring advanced circuit design and mature core algorithms, combined with a unique exterior, the MS400 holds multiple patents for software and appearance. It can detect 1–4 gases simultaneously, with freely switchable units, supporting over 500 types of gases. With unmatched versatility, performance, and value, the MS400’s water-resistant portable design is suitable for a wide range of applications.
