Outfitted with rapid-response MSA XCell® sensors, the ALTAIR 4XR Gas Detector is the toughest 4-gas monitor on the market and is backed by a 4-year warranty.

The ALTAIR 4XR can also provide real-time incident awareness to team members, supervisors, safety managers and others when paired with the MSA ALTAIR Connect app via a Bluetooth® wireless connection.

Simultaneously measures up to four gases from a wide range of XCell(R) sensor options including combustible gases, Oâ‚‚, CO, Hâ‚‚S, SOâ‚‚ and NOâ‚‚. The ALTAIR 4XR Detector surpasses industry standards in several crucial areas. Its four year sensor life is 60% longer than the industry average, while its 24 hour run time exceeds the industry average by 71%.

This versatile portable detector is a perfect match for industries ranging from fire fighting to welding, and its digital sensor output makes it less likely to suffer from RF interference. The unit features exclusive MotionAlert™, which lets others know if the user has become immobile, and InstantAlert™, a manual alarm that alerts others of potentially dangerous situations. This rugged unit is designed to withstand a drop of up to 20 ft (6m) and uses less than half as much calibration gas as the industry average.
