Altair 4X Mining Multigas Detector by MSA

MSA’s new ALTAIR 4X Mining Multigas Detector is driven by XCell Sensor Technology with ASIC design.Technology offers durability and performance for mining applications. Methane-optimized catalytic bead sensor provides increased stability over time. Dependable multigas detector tests for LEL, oxygen, carbon monoxide, and hydrogen sulfide.


  • Methane-optimized catalytic bead sensor provides increased stability over time
  • Sensor response and clear times in less than15 seconds
  • Reduces gas usage for bump testing and calibration
  • Greater accuracy and repeatability within changing environmental conditions
  • Temperature, humidity and pressure
  • Digital sensors offer increased RF (radio frequency) immunity
  • Eliminate false alarms from radios
  • Accurate CO readings from 0-2000 ppm
  • Industry-first CO/NO2 combination sensor with wide range and fast response times
  • Increased methane sensor poison resistance decreases down time and frequency of sensor replacements
  • End-of-sensor life warning gives advanced notice of failing sensors
  • Sensor life that greatly exceeds industry average

Lasting Durability

  • IP67 ingress protection rating
  • Dust-tight
  • Water-tight while completely submerged in 3 feet of water for 60 minutes
  • Withstands extreme impacts with rugged polycarbonate housing
  • Passes 20-ft drop test onto concrete
  • Rubberized instrument over-molding acts as an additional armor shield
  • Available in standard charcoal color or high-visibility glow-in-the-dark
  • Patented catalytic bead support wire protects methane sensor from shock

Life-Saving Performance

  • 24-hour compliance tick mark display indication
  • Clear visual indication of testing and operational compliance
  • Available for up to 4 gases within one small package (CH4, CO, O2, H2S, or NO2)
  • Large back-lit LCD display makes measurement readings easy to see
  • Loud 95dB audible horn
  • Four bright LED lights on all instrument corners make alarms visible from all directions
  • Selectable MotionAlertTM feature uses internal accelerometer to indicate "man down" and sound alarm
  • Compatible with MSA Galaxy Automated Test System for bump testing, calibrating, downloading, and report generation.
  • 30+ hour battery run time
