Description
Overview
This GAOTek Methane Gas Detector is used for portable and fast detection of the concentration of methane gas, temperature and humidity measurement (optional), and alarms for exceeding standards. The 3.5-inch high-definition color screen is used to display the concentration in real time, and imported brand gas sensors (Honeywell, Japan Fundamental, British CITY, British Alpha, British Dynament, Swiss Membrapor, etc.) are selected. The main detection principles are: electrochemistry, infrared, catalytic combustion, Thermal conductivity, PID photoion. It can detect the gas concentration in the pipeline or in the confined space and the atmospheric environment. It can detect the gas leakage or the purity of a high-concentration single gas with nitrogen or oxygen as the background gas. It can detect more than 500 types of gases.
Features
