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. Altair 2XP Gas Detector – with Xcell Pulse Technology First stand-alone bump test! The Altair 2XP gas detector provides a bump test that is so easy to follow, anyone can do it, from anywhere! the science behind this first-of-its-kind technology will change the face of portable gas detection as we know it. By combining pulse sensor interrogation with a simple flow check, we’ve created the first successful stand-alone bump test. Pulse sensor interrogation begins, exhale into the unit. and the result? You’re BUMPED!

Altair 2XT – Two-Tox Gas Detector The Altair 2XT detector eliminates the need for a second detector by utilizing proven Xcell two-tox Sensors. Xcell two-tox Sensors detect two gases on distinct sensor channels with digital output that minimizes cross channel interference.

Altair 2X – Single Gas Detector MSA revolutionized gas detection with Xcell Sensor technology. By miniaturizing the sensors’ controlling electronics and placing them inside the sensor itself using MSA’s proprietary application-specific integrated circuit (ASIC) design, MSA Xcell Sensors offer superior stability, accuracy, and sensor life.
