Description
Overview
GAOTek Combustible gas detector is a high performance fixed gas detector developed by our company, which is used for long-term continuous monitoring of combustible toxic and harmful gases in the air. It can continuous detect max 4 kinds of gas and display really timely, detect gas concentration by Natural diffusion. The standard 4 gas are CO O2 H2S and combustible gas, other gas can be combined flexibly.
