4 Gas Monitors

A 4-gas meter measures carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustible (EX-LEL) gases. Used for confined spaces such as tanks, vessels, silos, and tunnels. Maritime, oil and gas, construction, mining, water, and wastewater are just some of the industries that make use of 4 gas monitors. For single gas detector options see our Toxic Gas Detector products.
