The compact MultiPro Confined Space Gas Detector offers an exceptional array of features in a small, rugged instrument. The front-mounted, backlighted LCD display gives real-time readings of up to four gases simultaneously. Three user-replaceable sensors and up to four channels will monitor O2, LEL and either CO or H2S, or use the innovative Duo-Tox™ dual-channel sensor (two toxic gas sensors in a single sensor housing) to measure CO and H2S simultaneously, offering four channels of gas detection in the space of three, without any cross interference.
