MSA ALTAIR Oxygen (O2) 19.5/23 Vol % Gas Detector (Adjustable) 

The Altair O2 gas detector from MSA is an economical, high performing monitor with the ability to detect oxygen depletion levels in industrial applications.

The oxygen version of the Altair accommodates a fast responding 20 series sensor.

The rugged suspension clip on the instrument will give you the confidence that it can be worn almost anywhere. 

Testing the Altair O2 monitor is important and a simple bump check can be carried out with a single button press.  Bump test results are shown on the screen for 24 hours and can be used as a checkmark.

Other testing equipment available for the Altair is the QuickCheck and the Galaxy which is a standalone calibration test system.
