Description
Overview
GAOTek handheld co2 gas detector is used for the occasions where rapid detection of carbon dioxide gas concentrations, temperature and humidity measurements, and over-standard alarm. It adopts a 2.31 inch high-definition color screen for real-time display and uses imported gas sensors from well-known brands. The main detection principles are electrochemical, infrared, catalytic combustion, thermal conductivity, PID. Advanced circuit design, mature kernel algorithm processing, unique shape design, has obtained several software work patents and appearance patents. It can detect the gas concentration in pipelines or confined spaces and the atmospheric environment. It can detect gas leaks or high purity single gas purity of various background gases such as nitrogen or oxygen. It can detect more than 500 kinds of gases.
