Description
Overview
GAOTek combustible gas detector is an intelligent high-performance detection instrument that can continuously monitor a variety of gases (combustible gas and toxic and harmful gases). The instrument uses more than 20 kinds of plug-and-play smart sensors, including electrochemical toxic gas sensor, oxygen sensor and catalytic combustion sensor, the sensor can be configured flexibly in any combination (a combustible gas sensor is required in the four-in-one) to meet the analysis and detection needs of different industries.
