ALTAIR 4X Multigas Detector with XCell Sensor Technology.
MSA XCell Sensors are a breakthrough in chemical and mechanical sensor design, enabling faster response and span calibration times.
Adding micro electronics inside the sensors provides more control and higher performance than previous generations

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.

MSA XCell Technology:

Built upon years of sensor design experience, MSA is revolutionizing sensor technology with breakthroughs in design that improve performance. With reliable, extended-life XCell Sensors, there’s no need to replace sensors after two years.

  • Sensor response and clear times in less than 15 seconds.
  • Bump test in less than 15 seconds.
  • 60-second span calibration time.
  • Greater signal stability and repeatability under changing or extreme environmental conditions.
  • Two-tox CO/H2S sensor with virtually no cross-channel interference.
  • The digital output of the sensors makes them much less susceptible to RF interference.
  • Typical life greater than four years
  • Laser-welded sensor housings eliminate opportunities for leaks.
  • Combustible sensor’s proprietary operating mode enhances poison resistance over the sensor’s life
  • End-of-sensor-life warning gives advanced notice to user, reducing service outages
Life-Saving Performance Lasting Durability
  • Large buttons and a bright display enable quick and easy operation even while wearing gloves.
  • If a user becomes disabled due to unforeseen hazards, the MotionAlert sensor will activate after 30 seconds.
  • The InstantAlert feature enables users to manually alert others of a dangerous situation with the push of a button.
  • Compatible with Galaxy® Test System.
  • MSA Link™ Pro and MSA Link Software-ready.
  • Global approvals for worldwide acceptance.
