MSA is always looking for ways to push the limits of portable gas detection. They achieved a major breakthrough with the ALTAIR 4X. Now MSA’s gone even further with its ALTAIR^® 5X Multigas Detector with integrated photoionization detection (PID). Featuring the most advanced sensors available in any portable gas detector, the ALTAIR^® 5X Multigas Detectors with PID outperforms and outlasts the competition.

Faster bump test and calibration times

Streamline your processes by eliminating a second calibration step for the SO₂ sensor. Spend less money on calibration gas for most common 5-gas configurations.

• Provides an industry-first LEL, O₂, CO, H₂S and SO₂ 60-second span calibration and 10-second bump test time

Equipped with an internal integral pump

Save on parts and external components with an integrated pump that’s easier to service.

• Recessed inlet provides improved durability with fewer snags

Powered by the fast MSA XCell_®

Enhanced safety with industry-leading accuracy, repeatability and response times.

• Typical savings of more than 50% on calibration gas, replacement sensors and maintenance
• Typical downtime decrease of more than 50% while bump testing the instrument, waiting for a gas response and waiting for instruments to clear

Built on durability

Spend less money on replacement sensors and purchase replacement instruments less frequently. Spend less time maintaining instruments, more time using them.

• Four-year sensor life on LEL, O₂, H₂S, CO, SO₂ and IR sensors—60% longer than industry average
• Three-year sensor life on NH₃ and Cl₂—with two-year warranty
• Three-year warranty on LEL, O₂, H₂S, CO, SO₂ and IR sensors
• IP65 rated for dust and water
