Multi Pro


The MultiPro confined space gas detector gives you Real-time readings of up to four gases simultaneously. With three sensors and up to four channels the MultiPro lets you monitor O2, LEL and either CO or H2S. What’s even better is the new DuoTox dual channel sensor means you can now measure CO and H2S simultaneously. This versatile pump has a rugged construction and an attacheable motorized pump is optional.

The MultiPro is highly recommended for use with the MultiPro IQ Express Docking Station, which also doubles an an automated bump test and calibration station.
