The Metravi GD-09-4M Portable Multi-Gas Detector can easily detect Explosive Gas (EX), Oxygen (O2), Carbon Monoxide (CO) and Hydrogen Sulphide (H2S) continuously and simultaneously.

It is widely used in areas where explosion-proofing is required or toxic gas leaks might occur, like underground channels, in the mining industry and warehouses.It can also be used in living environments like homes, offices, restaurants, hotels, etc. It is a useful tool which helps protect lives and avoid damage to relevant equipment.
