Description
Overview
GAO Tek multi-gas analyser 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-inch high-definition colour screen is used to display the concentration in real time, and gas. The main detection principles are electrochemical, infrared, catalytic combustion, Thermal conductivity, PID photo ion.
Features
- Waterproof, dustproof, explosion-proof, shockproof, and anti-static
- Quick response with >10m sampling distance
- Simultaneously detects 1-5 gases with flexible unit options
- Offers three display modes, including real-time curves
- Enhances linearity and accuracy
- Automatic error identification, reducing human errors
