GWE4B Portable gas detector is used for rapidly detecting a variety of gas concentrations and ambient temperature and humidity, the measurement exceeds the limit value. It will show sound and light vibration alarm. Using 2.31 inch HD color screen real-time display. The main detection principles are: electrochemical , infrared, catalytic combustion, thermal conductivity, PID photoion and so on. Advanced circuit design, mature kernel algorithm processing, unique shape design. It is suitable for detecting gas concentrations in pipelines or confined Spaces and atmospheric environments; Gas leakage or a variety of background gas for nitrogen or oxygen high concentration of a single gas purity, more than 500 types of detected gases.
