Multi-Gas Monitor

The handheld MG140 multi-gas monitor from Industrial Scientific Corp. is ideal for confined space applications. The MG140 continuously monitors the surrounding air and displays the concentration of oxygen, combustible gas, carbon monoxide and hydrogen sulfide. A 90-dB audible alarm and ultra-bright visual alarm alerts the user when gas concentrations exceed preset limits. The highly visible, yellow enamel-coated stainless steel case provides durability, yet weighs just 24 oz. (680 grams) and measures a compact 4.75-in. by 2.75-in. by 1.65-in. (121mm by 70mm by 42mm). The instrument can be powered either by rechargeable Ni-Cad or replaceable 9-volt alkaline batteries.
