Effective December 31, 2015, the Sirius® Multigas Detector will be discontinued.

The replacement product, ALTAIR® 5X with PID, is now readily available for all of your gas detection needs.  The ALTAIR 5X with PID provides all of the benefits found in the ALTAIR 5X instrument family now with additional PID detection capability!  Built upon durability and featuring MSA's industry-leading XCell® Sensors for toxic, combustible and oxygen detection, the ALTAIR 5X is the preferred multigas detector for thousands of customers worldwide.

MSA intends to support existing Sirius Multigas Detectors with spare parts for two years from the discontinuation date, or until the parts are no longer available.  Thank you in advance for your cooperation and understanding.  Please contact your MSA Sales Manager or MSA Customer Service if you have any questions 1-800-672-2222.
