Driven by advanced MSA XCell Sensor Technology, the ALTAIR 5X Gas Detector delivers faster response time, better stability, accuracy, longer service life, and cost savings over the life of the instrument.
  
  
  • Detects combustible gases in LEL and/or volume percentage range, oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur dioxide, ammonia, chlorine, VOCs, and many others depending upon sensor configuration.
  • Rugged over-molded polycarbonate housing provides unsurpassed durability, including ability to survive 10-ft. (3m) drop; IP65-certified.
  • Field-proven integral pump provides consistent gas flow, eliminating concerns of externally-attached components.
  • High performance XCell Sensors last longer:
  • Typical life greater than 4 years for combustible, O2, CO/H2S, SO2, CO/NO2 and CO (high concentration) sensors.
  • Typical life greater than 3 years for NH3 and Cl2 sensors.
  • Most sensor response and clear times 15 seconds.
  • Less calibration gas used:
  • Requires about half of test gas typically used for calibration and bump tests.
  • Rapid bump test gives results in less than 10 seconds for most common sensor configurations.
  • Span calibration time of 60 seconds for most common sensor configurations.
  • MotionLO Alert feature option tells others that user has become immobile.
  • InstantAlert feature provides manual alarm to alert others as to a potentially hazardous situation.
  • PID option allows for accurate, reliable VOC response with programmable reference factors.
  • Large buttons and bright display provide easy operation, even when users wear gloves.
  • Exclusive end-of-sensor warning cautions users when unit's sensor nears end-of-life.
  • Versatile MSA Link™ Software allows users to transmit data to a computer.
  • Compatible with GALAXY® GX2 Test System and MSA Link Pro Software for fleet management.
  • Wireless Bluetooth included standard.
