Home & Worksite Safety

Fitted with advanced rapid-response MSA XCell® sensors, the ALTAIR 4XR Gas Detector is the toughest 4-gas confined space monitor available. The ALTAIR 4XR can also provide real-time incident notifications to team members, supervisors, safety managers, and others when paired with the MSA ALTAIR Connect app via a Bluetooth® wireless connection.

The GX-3R is the world's smallest 4 gas monitor weighing only 3.52 ounces and can comfortably be clipped within a worker’s breathing zone (2.2” W x 2.55” H x 1.02” D). It simultaneously monitors and displays LEL combustibles, O2, CO (Hydrogen compensated CO also available), and H2S.
