Overview
Enviro Testers hydrogen gas detector offers a simple portable solution for the widest array of toxic gas and oxygen (O2) applications on the market. In addition to typical sensors such as carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen (NOx), ammonia (NH3) and sulfur dioxide (SO2), we offer less-common sensors including hydrogen chloride, hydrogen fluoride, phosphine, ozone, ethylene oxide, methyl mercaptan, arsine and phosgene. The monitors have a large LCD providing maximum readability in the field and are made with six bright red LEDs allowing for a quick alarm notification. Constructed of strong and durable material, the product is designed to be comfortable yet drop-resistant. This product can easily be bump tested and calibrated either manually or using the convenient Single Docking Box, or 4-Bay Cali Case
