MS500 Handheld Five-in-One Gas Detector
The MS500 handheld five-in-one gas detector is designed for rapid detection of multiple gas concentrations, temperature and humidity measurement, and over-limit alarm applications.
Featuring a 2.5-inch high-definition color screen for real-time concentration display, the MS500 utilizes top-tier gas sensors from leading industry brands. Its detection principles include:
With advanced circuit design and sophisticated core algorithm processing, the MS500 has obtained multiple software copyrights and design patents.
This detector is capable of measuring gas concentrations in pipelines, confined spaces, and ambient air, as well as detecting gas leaks and high-purity single gases (with nitrogen or oxygen as background gases). It supports over 500 types of detectable gas
