MSA Altair® 5X Multigas Detector

ALTAIR 5X Multigas Detector with XCell Sensor Technology

MSA’s new ALTAIR 5X Multigas Detector is driven by the most advanced technology available in any portable gas detector on the market. Breakthroughs in design improve performance and ensures that the ALTAIR 5X Multigas Detector outlasts the competition.


  • The MSA ALTAIR 5X Detector allows for an industry-first LEL, O2, CO, H2S, and SO2 60-second span calibration and 10-second bump test time. Elimination of a second calibration step for the SO2 sensor. Save money on calibration gas for the most common 5-gas configuration in the market.

    • The MSA ALTAIR 5X Multi-Gas monitors equipped with an internal integral pump. Savings on spare parts and external components by having an integrated pump that is easier to service.

      • The ALTAIR 5X Detector is powered by the fast MSA XCell® sensor family including the introduction of 3 new sensors. Cost savings of over 50% on calibration gas, replacement sensors, and maintenance. Decrease in downtime of over 50% while bump testing Enhanced safety with industry-leading accuracy, repeatability, and response times.

      • 4-year expected sensor life on LEL, O2, CO, H2S, SO2, IR, and standard 3-year instrument warranty. 3-year expected sensor life on NH3, Cl2, and standard 2-year warranty.Cost Savings on replacement sensors and purchase replacement instruments less frequently. Spend less time maintaining instruments, more time using them.

      • The ALTAIR 5X portable gas detector provides an industry-exclusive end-of-sensor-life-warning to save money and aggravation by reducing Instrument downtime and sensor inventory.

      • MotionAlert™ feature - “man-down” alarm- and InstantAlert™ feature - manual alarm, offer additional ways to call for help and send out a warning. Ideal for confined space applications when there is no direct line of sight .

      • The ALTAIR 5X gas monitor is durable, providing industry - leading impact resistance.
