You save £140.00 (26%)
The MSA Altair 4X is a precision-engineered portable multigas detector that sets a high benchmark for industrial safety by monitoring up to four gases simultaneously. Built with exclusive XCell sensor technology, this unit delivers a 24-hour runtime and a four-year sensor life, significantly outperforming industry averages. Designed for extreme environments, the detector features a rugged housing capable of withstanding a 20 ft (6m) drop while utilizing advanced digital sensor outputs to minimize RF interference.
What gases can be monitored with the MSA Altair 4X?
The Altair 4X measures up to four gases simultaneously from options including combustible gases, Oxygen (O2), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Sulfur Dioxide (SO2), and Nitrogen Dioxide (NO2). Its XCell sensors ensure accurate detection for applications ranging from fire fighting to welding.
How durable is the MSA Altair 4X for industrial use?
This unit is exceptionally rugged, designed to survive a 20 ft (6m) drop and engineered for low calibration gas usage to reduce maintenance costs. Its IP-rated construction and digital sensor resilience make it a reliable tool for confined space entry and toxic gas detection.
What safety alarms are included in the MSA Altair 4X?
The detector includes the exclusive MotionAlert system, which signals others if the user becomes immobile, and the InstantAlert manual alarm for emergency situations. These integrated safety features provide critical communication capabilities in dangerous industrial or rescue environments.
