ALTAIR® 4X Multigas Detector

The ALTAIR 4X is an extremely durable Multigas Detector that simultaneously measures up to four gases from a wide range of XCell(R) sensor options including combustible gases, O₂, CO, H₂S, SO₂ and NO₂. The ALTAIR 4X Detector surpasses industry standards in several crucial areas. Its four-year sensor life is 60% longer than the industry average, while its 24-hour run time exceeds the industry average by 71%. This versatile portable detector is a perfect match for industries ranging from fire fighting to welding, and its digital sensor output makes it less likely to suffer from RF interference. The unit features exclusive MotionAlert™, which lets others know if the user has become immobile, and InstantAlert™, a manual alarm that alerts others of potentially dangerous situations. This rugged unit is designed to withstand a drop of up to 20 ft (6m) and uses less than half as much calibration gas as the industry average. 

  • Dependable multigas detector tests for LEL, oxygen, carbon monoxide, hydrogen sulfide, sulfur dioxide and nitrogen dioxide
  • Economical construction saves users more than 50% on calibration gas, replacement sensors and maintenance
  • Four-year sensor life means detector lasts 60% longer than the industry average
  • Unit uses 50% less calibration gas per minute than the average detectors within the industry
  • Two-tox CO/H2S sensor removes practically all cross-channel interference
  • Large buttons and high-contrast screen make operation easy in low-light conditions
  • Ribbed rubber housing provides secure grip and high durability
  • Unit features 95+ db alarm and ultra-bright LEDs
  • Exclusive end-of-sensor warning cautions user when unit's sensor needs to be changed
  • MotionAlert option tells others that user has become immobile
  • InstantAlert provides manual alarm to alert others of a dangerous situation
