MSA Safety Works ALTAIR 4XR Multigas Detector – LEL/O₂/H₂S/CO-H₂, Charcoal
Product Overview
The MSA Safety Works ALTAIR 4XR is a compact, rugged four-gas detector designed for professional atmospheric monitoring. This configuration combines LEL, oxygen (O₂), hydrogen sulfide (H₂S), and hydrogen-resistant carbon monoxide (CO-H₂) detection in a single portable instrument.
The CO-H₂ sensor is the key feature of this configuration. It is designed to reduce the effect of hydrogen on the CO measurement, making this version useful for applications where hydrogen may be present.
The detector has a charcoal-colored housing and is supplied in this configuration with a North American charger.
Key Features
Monitors LEL, O₂, H₂S, and CO-H₂
Hydrogen-resistant CO sensor configuration
Compact and lightweight handheld design
Durable charcoal-colored housing
LCD display
Audible, visual, and vibrating alarms
MotionAlert feature
InstantAlert emergency notification
Rechargeable lithium-polymer battery
Approximately 20 hours of operating time with Bluetooth off under specified conditions
IP68 ingress protection under specified test conditions
Designed for professional industrial and field applications
Gas Detection Configuration
| Sensor | Function |
|---|---|
| LEL | Monitors combustible gases relative to the Lower Explosive Limit |
| O₂ | Measures oxygen concentration |
| H₂S | Detects hydrogen sulfide |
| CO-H₂ | Measures carbon monoxide using a hydrogen-resistant CO sensor |
Typical Measuring Ranges
| Gas | Measuring Range | Resolution |
|---|---|---|
| Combustible / LEL | 0–100% LEL | 1% LEL |
| O₂ | 0–30% volume* | 0.1% volume |
| CO | 0–1,999 ppm | 1 ppm |
| H₂S | 0–200 ppm | 1 ppm |
*The O₂ sensor is certified for 0–25% by volume. MSA's technical documentation also lists the CO-H₂ sensor as having a 0–1,999 ppm range and a 1 ppm resolution.

MSA's published technical data specifies the ALTAIR 4XR at 224 g with battery and clip and 112 × 76 × 33 mm without the fastening clip in its general technical documentation, while the specific 10179330 product listing gives 230 g and 118 × 75 × 58 mm. For an ecommerce listing, the latter should be treated as the SKU-specific dimensions and weight.
Hydrogen-Resistant CO Sensor
The CO-H₂ configuration distinguishes this model from the standard ALTAIR 4XR equipped with a conventional CO sensor.
MSA's performance documentation identifies the hydrogen-resistant CO sensor as having a 0–1,999 ppm CO range, 1 ppm resolution, and specified hydrogen resistance of less than 5%.
This makes the configuration particularly relevant where hydrogen may be present and CO monitoring is also required. The CO-H₂ sensor should not, however, be interpreted as a detector for hydrogen itself—the LEL sensor is used for combustible-gas monitoring.
Rugged Field Design
The ALTAIR 4XR is built for portable use in demanding work environments. Its enclosure is rated IP68 under MSA's specified test conditions, providing protection against dust and water ingress.
The detector also provides several alarm methods, including audible, visual, and vibration alerts, so operators can recognize hazardous conditions even when they are not continuously looking at the display.
Battery & Operation
The ALTAIR 4XR uses a rechargeable lithium-polymer battery. MSA specifies a typical runtime of approximately 20 hours at 25°C with Bluetooth disabled. Runtime can decrease when Bluetooth is enabled or when the backlight is configured to remain on. Charging time is specified at up to approximately 4 hours.
MotionAlert & InstantAlert
Two additional functions help support worker safety:
MotionAlert can indicate when the instrument detects a lack of movement from the user.
InstantAlert allows the operator to manually trigger an emergency alarm.
These functions can provide additional notification during confined-space and field operations.
Typical Applications
The ALTAIR 4XR can be used for atmospheric-monitoring tasks in:
Confined-space entry and pre-entry testing
Oil and gas operations
Plant maintenance
Construction
Mining
Utilities
Fire and emergency response
General industrial inspections
Welding-related environments
Work areas where hydrogen may be present
What's Included
The specific MSA 10179330 configuration consists of:
1 × MSA ALTAIR 4XR Multigas Detector
LEL sensor
O₂ sensor
H₂S sensor
CO-H₂ sensor
Charcoal housing
North American charger
Sampling pumps, probes, calibration cylinders, regulators, carrying cases, and other accessories are not assumed to be included unless specifically stated in the seller's package description.
Important Safety Information
The ALTAIR 4XR is a professional gas-detection instrument and should be operated by personnel trained in atmospheric monitoring and gas-detector procedures.
Before use, verify the instrument's sensor configuration, calibration status, alarm settings, and applicable approvals. Regular bump testing and calibration should be performed according to MSA's current instructions and the requirements of the applicable workplace safety program.
The displayed measuring ranges should not be confused with certification limits. For example, MSA specifies that the O₂ sensor's 0–30% display range is certified only through 25% O₂.
Summary
The MSA Safety Works ALTAIR 4XR 10179330 is a professional four-gas detector configured for LEL, O₂, H₂S, and hydrogen-resistant CO (CO-H₂) monitoring.
Its rugged charcoal housing, compact design, IP68 protection, rechargeable battery, multiple alarm methods, MotionAlert, and InstantAlert make it well suited to demanding industrial environments. The CO-H₂ sensor is the defining feature of this configuration, providing a specialized option for applications where hydrogen may affect conventional CO measurements.
