Description
Overview
GAOTek hydrogen sulfide gas detector could detect combustible gas, O2, and other two types of toxic gases continuously and simultaneously. It is widely used in the area where explosion proof is required or toxic gas leaks, like underground channels or the mining industry, to protect the workers’ life and avoid damage to the relevant equipment.
