MSA ALTAIR 5X Multigas Detector

The MSA ALTAIR 5X Multigas Detector combines advanced sensor technology, an internally integrated pump, and rugged construction to deliver reliable gas detection in demanding environments. Configurable to monitor up to six gases simultaneously, it is ideal for confined-space entry, industrial safety, emergency response, and remote sampling applications.

Fast, Efficient Gas Detection

Powered by MSA XCell® Sensor technology, the ALTAIR 5X delivers fast response times while reducing calibration time, gas usage, and ongoing maintenance costs.

• Detects LEL, O₂, CO, H₂S, SO₂, and other available gases
• Monitors up to six gases simultaneously
• 60-second span calibration for common five-gas configurations
• 10-second bump testing
• Response and clear times under 15 seconds for LEL, O₂, CO, H₂S, and SO₂
• Uses approximately 40% less calibration gas per minute than the industry average
• End-of-sensor-life warning helps reduce unexpected downtime
• Optional IR sensors are available for gases and ranges including CO₂

Built for Demanding Environments

The ALTAIR 5X is housed in rugged polycarbonate and engineered to withstand harsh working conditions. Its internally integrated sampling pump eliminates the need for externally attached pump components while providing consistent gas flow for remote monitoring.

• Withstands a 10-foot drop
• Internally integrated, field-proven sampling pump
• Durable, glove-friendly controls
• High-contrast display for improved visibility
• Ergonomic design for easier operation in the field
• Optional glow-in-the-dark housing on select IR-equipped models

Advanced MSA XCell Sensor Technology

MSA XCell Sensors incorporate their controlling electronics directly into the sensor through a proprietary application-specific integrated circuit design. This provides greater stability, accuracy, repeatability, and performance under changing environmental conditions.

• Four-year expected sensor life for LEL, O₂, CO, H₂S, SO₂, and IR sensors
• Three-year expected sensor life for NH₃ and Cl₂ sensors
• Faster calibration and response times
• Reduced replacement-sensor and maintenance costs
• Stable performance in changing or extreme conditions
• Three-year warranty on LEL, O₂, CO, H₂S, SO₂, and IR sensors

Worker-Safety Features

Exclusive MSA safety features provide additional protection when personnel are working alone or in hazardous areas.

• MotionAlert™ activates when the instrument detects that the user has become motionless
• InstantAlert™ allows the user to manually warn others of a hazardous condition
• Audible, visual, and vibrating alarms provide clear hazard notification
• Well suited for confined-space monitoring and remote sampling

Flexible Configuration

The ALTAIR 5X can be configured for various applications using interchangeable, plug-and-play sensor slots. Available display and power options allow departments and safety teams to select the configuration that best meets their operational needs.
