MS500 Portable Dust Detector
MMS500 is a multifunctional portable gas detection instrument designed for fast, accurate measurement of toxic and hazardous gases, as well as temperature and humidity. It can be used for detecting gas concentrations in pipelines, confined spaces, ambient air, gas leaks, or high-purity background gases such as ammonia or oxygen. With a detection capacity covering more than 500 gas types, it provides reliable safety monitoring in various industrial environments.
Equipped with a 2.5-inch high-definition color display, the MS500 provides clear real-time readings. The device supports single or multi-channel detection and displays real-time concentration curves.
