About This Product
The MSA ALTAIR 4XR is a rugged multi-gas detector simultaneously monitoring LEL (combustibles), O2, CO, and H2S with rapid-response XCell sensors. It operates from -40F to +140F, survives drops from 25 feet onto concrete, and carries IP68 waterproof rating (2m for 60 minutes). Essential for HVAC technicians entering confined spaces, mechanical rooms, and boiler plants where combustible gas accumulation or oxygen depletion may occur. Backed by MSA's 4-year factory warranty.
