Option for detect below gases:

  • MSA ALTAIR Pro detect CO
  • MSA ALTAIR Pro detect H2S
  • MSA ALTAIR Pro detect O2
  • MSA ALTAIR Pro detect NH3
  • MSA ALTAIR Pro detect Cl2
  • MSA ALTAIR Pro detect ClO2
  • MSA ALTAIR Pro detect NO2
  • MSA ALTAIR Pro detect SO2
  • MSA ALTAIR Pro detect HCN

Based on the industry-standard ALTAIR Single-Gas Detector—but with added features and functionality—ALTAIR Pro toxic gas and oxygen detectors combine reliable detection and LED/audible/flashing/vibrating alarms with clear, backlit LCD displays. Electrochemical sensors measure concentrations of toxic gas (chlorine dioxide, hydrogen cyanide and phosphine) or percent oxygen. Purpose-built for superior dust and water protection, excellent impact resistance and excellent RFI performance.


  • Unit detects O2, ClO2, HCN and PH3
  • Gas concentration (chlorine dioxide, hydrogen cyanide and phosphine) or percent oxygen displayed on a large, clear, backlit LCD
  • Automatically records the last 50 alarm/test events while simultaneously recording peak gas readings or low O2 readings every three minutes in a periodic data log
  • User can read data or change alarm set points by connecting unit to MSA Link via built-in IR communication port
  • Adjustable alarm set points
  • No-miss quad alarm system includes bright flashing LEDs, piercing audible alarm, LCD notification, and an internal vibrating alarm
  • Rubberized armor housing and one-button operation for maximum durability and simplicity
  • Easy alarm check, bump check, fresh air zero, and calibration
  • Easily replaceable batteries and sensors
  • Markets: Contractor, Contractor, Industrial, Mining, Oil & Gas, Utilities
  • Applications: Toxic Detection, Oxygen Detection
