Workers who face potentially dangerous situations deserve the best protection available. At MSA, we work tirelessly to build smarter, better gas detection instruments that people across the world can rely on. To that end, we are proud to introduce the next level of advanced technology available in any portable gas detector on the market: The ALTAIR 4X multi-gas detector with MSA XCell Sensor Technology.

The ALTAIR 4X is a reliable multi-gas detector that measures O2, H2S, CO and combustible gas. A rugged housing provides unsurpassed durability, including the ability to survive a 6 m drop test onto concrete. And with large, glove-friendly buttons and a high-contrast display, the ALTAIR 4X is easy to operate in any work environment, even low-light conditions.

Multifunctional Alarms
Exclusive safety features like MotionAlert and InstantAlert make the ALTAIR 4X ideal for applications like confined space entry. The MotionAlert sensor activates when the user is overcome and requires assistance, quickly alerting others to the disabled user’s location. And with a simple push of a button, the InstantAlert feature enables users to manually alert others to potentially hazardous situations.

MSA XCell Sensor Technology- Powered by Performance
Toughness and durability aren’t the whole story. The real strength of the ALTAIR 4X comes from the new MSA XCell Sensor Technology. Building on years of sensor design experience, MSA has revolutionized sensor technology by changing chemical composition, reducing physical size and adding micro-electronics inside the sensor. This unique combination enables the XCell Sensors to speed up response, clear and calibration times. MSA XCell Sensors offer superior stability, accuracy, repeatability, and an extended life-time.

Sensor Options:
► MSA XCell Combustible Sensor
► MSA XCell Oxygen Sensor
► MSA XCell CO/H2S Sensor
