ALTAIR 4XR Multigas Detector

The MSA ALTAIR 4XR gas detector is a portable multi-gas device designed for use in hazardous environments such as confined spaces, industrial maintenance, or emergency response. The 4XR can simultaneously detect up to four gases: flammable liquids (LEL), oxygen (O), carbon monoxide (CO), and hydrogen sulfide (HS), all of which are common industrial hazards. It features an XCell® sensor that responds two times faster than standard industrial sensors, enabling immediate detection of hazardous conditions.
