Description
Overview
GAOTek Multi Gas and Carbon Monoxide Gas Detector is used for portable and rapid detection of toxic and harmful gas concentration, temperature and humidity measurement and exceeding the standard alarm. a 2.5 in high-definition color screen is used to display the concentration in real time, and gas. The main detection principles are electrochemical, infrared, catalytic combustion, Thermal conductivity, and PID photo ion.MS500 can detect the gas concentration in the pipeline or in the confined space and atmospheric environment.
Features
- Waterproof, dustproof, explosion-proof, shockproof
- Quick response with >10m sampling distance
- Simultaneously detects 1 gas to 5 gases with flexible unit options
- Offers three display modes, including real-time curves
- Enhances linearity and accuracy
- Automatic error identification, reducing human errors
