Introducing the Altair 2X gas detector from MSA; the first one or two gas detector that incorporates industry-leading Xcell Sensor technology to deliver unparalleled performance while drastically minimizing total cost of ownership, increasing durability and delivering enhanced worker safety, compliance and traceability. The Altair 2X is also the first portable gas detector to introduce revolutionary Xcell pulse technology. Based on proven science and advanced patented sensor capabilities, the Altair 2Xp detector delivers the world’s first stand-alone bump test. This allows a daily bump test to be performed without the need for calibration accessories or specific calibration gas.


"With our patented Xcell pulse technology, we have created a simple and inexpensive approach to bump testing. Years of scientific research, patented sensor interrogation technology and proprietary sensor response methodologies have delivered the world’s first gas detector with a stand-alone bump test. Simply put; the use of calibration accessories or bottled calibration gas is not required for bump testing the Altair 2XP Gas Detector."


 Like all MSA Detectors, Altair 2X is built for durability and designed for   the work that is being completed. 

 • Withstands extreme impacts with rugged polycarbonate housing and     passes 25-foot drop test
 • IP 67-rated altair 2X is both dust tight and water tight
 • Minimal RF interference
 • Full three-year warranty supports the entire instrument, including the     sensors.

 Reduced Costs and Expense

 • Xcell Sensor response and recovery time reduces the gas   consumption for calibration and gas bump tests (where applicable).

 • The Altair 2XP with XCell Pulse Technology reduces the need for     specific calibration gas and bump test accessories providing   significant   savings!

 • The Altair 2XT Two-Tox eliminates the need for a second instrument in   several applications.

Increased productivity

 • Skip the gas line! – the stand-alone bump test on the Altair 2XP means
 that you will be spending more time doing the job and less time   waiting  in line or conducting bump tests. Spending less time at the   bump station means less down time and more time producing!

 • Faster bump tests, easy compliance and product reliability means     you  can get to work faster and safer!
