MSA Safety Works ALTAIR 4XR Multigas Detector – LEL, O₂, H₂S & CO
Product Overview
The MSA Safety Works ALTAIR 4XR Multigas Detector is a portable four-gas instrument designed to monitor combustible gases (LEL), oxygen (O₂), hydrogen sulfide (H₂S), and carbon monoxide (CO).
This configuration uses a charcoal-colored housing and is supplied with a North American charger. It is designed for professional users who need continuous personal gas monitoring in demanding industrial environments.
The ALTAIR 4XR combines a compact handheld design with a rechargeable battery, LCD display, audible and vibration alarms, and bright gas alarm indicators. It is suitable for applications such as confined-space entry, maintenance, oil and gas operations, utilities, construction, mining, and emergency response.

Gas Detection Specifications
| Gas | Sensor Type | Measuring Range |
|---|---|---|
| Combustible / LEL | Catalytic | 0–100% LEL |
| Oxygen (O₂) | Electrochemical | 0–30% volume* |
| Hydrogen Sulfide (H₂S) | Electrochemical | 0–200 ppm |
| Carbon Monoxide (CO) | Electrochemical | 0–1,999 ppm |
*The O₂ sensor is certified for 0–25% volume O₂ according to the manufacturer's technical documentation.
The detector measures the four gases simultaneously and displays the corresponding gas concentrations on its LCD screen. The exact alarm settings should be confirmed on the individual instrument because alarm values can be configured according to the applicable workplace requirements.

MSA's product page gives the 10178557 dimensions as 118 mm long × 75 mm wide × 58 mm high and weight as 0.230 kg. The technical manual gives 224 g for the device with battery and clip and uses a different measurement basis for dimensions, so the product-page figures above are the more appropriate listing specifications for this exact part number.
Alarm and Monitoring System
The ALTAIR 4XR uses multiple warning methods to help make hazardous gas conditions noticeable:
Four gas alarm LEDs for visual notification
Audible alarm rated at approximately 95 dBA at 30 cm
Vibration alarm for tactile notification
LCD display showing gas concentrations and instrument status
Charge-status LED for battery information
Using different alarm methods helps the wearer recognize an alarm even when the display is not directly visible or the working environment is noisy.
Battery and Charging
The detector is powered by a rechargeable lithium-polymer battery. MSA specifies approximately 20 hours of operating time at 25°C with Bluetooth disabled.
Runtime can be reduced when additional power-consuming features are enabled. MSA indicates a nominal reduction of about 10% with Bluetooth enabled and about 15% when the backlight is configured to remain on. Charging takes 4 hours or less under the specified conditions.
The rechargeable battery must not be charged in an Ex hazardous area.
Rugged Field Design
The ALTAIR 4XR is built for professional field use. Its IP68 rating provides a high level of protection against dust and water, with the manufacturer's test specification covering immersion at 2 meters for 45 minutes.
The detector's operating specifications include a normal temperature range of -10°C to 40°C, with an extended operating range reaching -40°C to 60°C, subject to the applicable sensor and approval limitations.
Typical Applications
The ALTAIR 4XR can be used for personal gas monitoring in environments such as:
Confined-space entry
Oil and gas operations
Plant maintenance
Industrial turnarounds
Utilities
Construction
Mining
Fire and emergency response
General industrial operations
Areas where combustible gases, oxygen deficiency/enrichment, CO, or H₂S may be present
The correct gas detector configuration should always be selected based on the specific hazards identified at the worksite.
Calibration and Maintenance
For dependable operation, the ALTAIR 4XR should be inspected and tested according to MSA's instructions and the requirements of the workplace gas-detection program.
Recommended practices include:
Inspecting the instrument before use
Performing required bump/functional tests
Calibrating the sensors at the required intervals
Checking alarm operation
Keeping the battery adequately charged
Replacing sensors or other service components when required
Maintaining records of calibration and testing
Calibration and testing requirements can vary depending on the workplace, gases being monitored, regulations, and company procedures.
Important Safety Information
The ALTAIR 4XR is a professional gas-monitoring instrument, not a substitute for a complete workplace safety program.
Always verify the detector's actual sensor configuration, alarm settings, approvals, and operating limitations before use. Do not assume that all ALTAIR 4XR models have the same gas sensors or accessories.
The rechargeable battery should only be charged in an appropriate safe area as specified by MSA. Regular bump testing, calibration, inspection, and maintenance are essential for reliable gas detection.
Summary
The MSA Safety Works ALTAIR 4XR Multigas Detector provides simultaneous monitoring of LEL, O₂, H₂S, and CO in a compact, rugged handheld instrument. The charcoal configuration combines four-gas detection with a rechargeable lithium-polymer battery, LCD display, multiple alarm types, and IP68 protection.
It is a practical choice for professionals who need portable gas monitoring for industrial maintenance, confined spaces, oil and gas, utilities, construction, mining, and emergency-response applications.
