Description
Overview
GAOTek Portable five-in-one toxic and harmful gas detector is used for portable and rapid detection of toxic and harmful gas concentration, temperature and humidity measurement and exceeding the standard alarm. 2.5 in (63.5 mm) 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, PID photo ion. It can detect the gas concentration in the pipeline or in the confined space and atmospheric environment. It can detect gas leakage or the purity of a single gas with high concentration of nitrogen or oxygen as the background gas. It can detect more than 500 kinds of gases.
Features
- Waterproof, dustproof, explosion-proof, shockproof, and intrinsically safe
- Detects 1 to 5 gases simultaneously, switchable units, and offers three display modes
- Multi-level calibration improves measurement precision
- Prevents calibration errors, ensuring reliable results
