MultiPro - Confined Space Gas Detector

MultiProReal-time readings of up to four gases simultaneously, one button operation and calibration, easy to read LCD display, audible and visual alarms, event logger, IrDA port, optional sample draw pump, rugged, compact and affordable - the MultiPro Confined Space Gas Detector.

MultiPro can be configured for your needs. Three sensors and up to four channels let you monitor O2, LEL and either CO or H2S, or using our innovative DuoTox dual channel sensor, measure CO and H2S simultaneously. DuoTox is actually two toxic gas sensors in a single housing, giving you four channels of direct detection in the space of three - without cross interference.

Plus, MultiPro is built tough. Ruggedly constructed of an engineered polycarbonate with a rubber overmould, MultiPro goes where you go. Interchangeable Alkaline (3 AA) and Li-Ion battery packs, and optional sample draw pump, and a range of accessories make MultiPro the most versatile and affordable gas detector on the market.
