Overview
Hospitality Enviro Tech portable four-in-one gas detector is mainly used to quickly and accurately detect gas leaks or alarms for excessive gas concentrations. The fourin-one detection module contains 1-4 digital sensors, each of which is plug-andplay and intelligently identified. The main detection principles of gas detection are: electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoionization , etc. widely used in firefighting, emergency rescue, confined spaces, petroleum, chemical industry, metallurgy, refining, gas, warehousing, medicine, environmental protection, air treatment and other occasions.
