Specification of Gas Detector MSA ALTAIR 4XR

Built on Durability

The ALTAIR 4X Multigas Detector for LEL, O2, CO, H2S (with CO-H2 res, H2S-LC, SO2 or NO2 option) is as tough

and functional as it looks. A rugged housing provides unsurpassed durability, including the ability to survive a 20-

foot drop. And with large, glove-friendly buttons and a high-contrast display, the ALTAIR 4X Multigas Detector is

easy to operate in any work environment, even low-light conditions.

Powered by Performance

Toughness and durability aren’t the whole story. The real strength of the ALTAIR 4X Multigas Detector comes from new sensor

technology. MSA XCell Sensors have a typical life of more than four years, double the industry average, and are engineered using

MSA’s proprietary application-specific integrated circuit (ASIC) design. By miniaturizing sensor controlling electronics and placing

them inside the sensor itself, MSA XCell Sensors offer superior stability, accuracy and repeatability.

MSA XCell Sensors are a breakthrough in chemical and mechanical sensor design, enabling faster response and span calibration

times. With less time spent on calibration and bump tests, you save calibration gas, maintenance costs and in turn, save money.

But most importantly, in your industry, saving seconds on response time can also mean saving lives.

Count on the ALTAIR 4X Detector

Exclusive safety features like MotionAlert™ and InstantAlert™ make the ALTAIR 4X Multigas Detector ideal for applications like

confined space entry. The MotionAlert sensor activates when a user becomes disabled and motionless, quickly alerting others to

the disabled user’s location. And with a simple push of a button, the InstantAlert feature enables users to manually alert others to

potentially hazardous situations.

The ALTAIR 4X Multigas Detector outlasts the competition. To prove it, the instrument comes with a full three-year warranty,

an entire year longer than the industry average, so that you can depend on the ALTAIR 4X Multigas Detector to withstand the

wear and tear that other portable gas detectors can’t.
