Description
Overview
GAOTek Infrared Sensor Methane Gas Detector can be used in the rapid detection of a variety of gas concentrations and measurements of environmental temperature and humidity, if the measurement exceeds the limit value, the alarm emits sound and light vibration. The main principles include electrochemical, infrared, catalytic combustion, thermal conductivity PID photoionization, etc. It is suitable for detecting the concentration of gases in the atmosphere environment, pipelines, or confined space.
