Altair 4X

The MSA Altair 4X all-in-one gas detector, measuring Ex/LEL O2 CO H2S (Optional NO2), meets all important industry standards, and uses a sensor that’s 60% longer than average. It is a versatile and perfect choice for a wide range of applications and industries: Built-in MotionAlert™ alarms to let outsiders know the user is inactive, and InstantAlert™ , the alarm indicates that a dangerous situation is occurring. The detector’s construction is sturdy, can be safely dropped from 20 feet, and uses less than a quarter of the standard gas than average.

MSA Altair 4X has officially stopped production from December 2018
