MSA Altair 4XR Multi Gas Detector

MSA Altair 4XR Multi Gas Detector

The MSA Altair 4XR Multi Gas Detector is a rugged and reliable industrial gas monitoring device designed for the most demanding and hazardous work environments. Built to withstand extreme conditions, this multigas detector delivers fast, accurate gas detection while maintaining durability that exceeds industry standards.

Outfitted with advanced MSA XCell sensors, the MSA Altair 4XR Multi Gas Detector is engineered to detect gas hazards up to two times faster than the industry average, helping workers respond quickly when safety is at risk. It is widely recognized as one of the toughest 4-gas monitors available today.

This product is part of our Gas Detection and Monitoring solutions for industrial safety.

Built for Extreme Durability

The MSA Altair 4XR Multi Gas Detector is designed for real-world industrial abuse. It is third-party certified to MIL-STD-810G and can survive 25 drops from 4 feet (1.2 meters) as well as an incidental 25-foot drop onto concrete. This exceptional durability makes it suitable for harsh environments such as mining, oil & gas, firefighting, and confined space operations.

The device operates reliably across a wide temperature range from -40°C to +60°C, ensuring consistent performance in both extreme cold and high-heat environments.

Fast and Accurate Gas Detection with XCell Sensors

At the core of the MSA Altair 4XR Multi Gas Detector are MSA’s proven XCell® sensors, known for rapid response times and long service life. These sensors enable quicker gas detection, improving worker reaction time and overall safety.

The detector supports multiple sensor configurations, including:

• Combustible (LEL)

• Oxygen (O₂)

• Toxic gases such as CO, H₂S, NO₂, and SO₂ (configuration dependent)

This flexibility allows the detector to be configured for specific site hazards.

Designed for Safety, Compliance, and Ease of Use

The MSA Altair 4XR Multi Gas Detector helps simplify compliance with safety procedures. The built-in Bump LED and on-screen checkmark allow users to quickly confirm that the instrument has passed functional tests.

Calibration and bump testing require up to 50% less test gas and time compared to industry averages. When used with the MSA GALAXY® GX2 Automated Test System, users can schedule bump tests and calibrations at a predefined time of day, reducing manual intervention.

Advanced Safety Alerts for Hazardous Situations

The detector includes advanced alert features designed to protect workers in dangerous conditions:

• MotionAlert notifies others if the user becomes immobile

• InstantAlert allows the user to manually signal a potentially dangerous situation

These features are especially valuable in confined spaces, emergency response, and lone-worker applications.
