Multi-Gas Detector 740 series
The 3M™ Multi-Gas Detector 740 Series was designed for monitoring confined work spaces, scenarios where potentially hazardous levels of CO, H2S, O2, or combustible gases may be found. Apart from its ability to detect up to four gases at a time, the 740 series detector features a bright, readable display, precalibrated sensor replacement packs, and heavy duty construction.
