Description
Overview
GAOTek Portable Multi Gas Detector could detect combustible gas, O2, and other 2 kinds of toxic gases simultaneously. It is widely used in areas where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, to protect the workers’ lives and avoid damage to the relevant equipment.
