Description
MSA Galaxy GX2 Calibration Unit automates ALTAIR gas detector bump testing and calibration for centralised, high-throughput fleet safety management.
The MSA Galaxy GX2 Calibration Unit is a fixed, automated bump testing and calibration station for MSA ALTAIR portable gas detectors. It initiates tests automatically on docking, reducing manual intervention and human error while helping to keep instruments accurate and compliant. With multi-instrument throughput, integrated charging, and full data access, it supports centralised management of extensive ALTAIR fleets. Combined with MSA Link™ Pro Software, it underpins audit-ready traceability, proactive gas-exposure monitoring, and consistent detector maintenance across demanding industrial environments.
AT A GLANCE
- Automated compliance workflows: Touch-free bump testing and calibration on docking reduces manual steps, operator error, and variability between tests.
- High-throughput fleet management: Simultaneous testing and charging of multiple ALTAIR detectors supports central hubs and large instrument populations.
- Integrated data and reporting: MSA Link™ Pro Software provides dashboard visibility, exposure alerts, and exportable records for audit-ready traceability.
- Scalable, rugged platform: Fixed, expandable architecture, clear visual status indicators, and multi-language interface suit global, multi-site deployment.

Overview of MSA Galaxy GX2 Calibration Unit
Automated, Touch-Free Compliance for ALTAIR Fleets
The MSA Galaxy GX2 Calibration Unit provides automated bump testing and calibration for MSA ALTAIR portable gas detectors, including ALTAIR, ALTAIR PRO single-gas and ALTAIR 2X, 4X, 4XR and 5X multigas models. Once an instrument is docked, the appropriate test sequence runs automatically without pressing any buttons. This touch-free process standardises procedures, reduces the risk of skipped steps, and supports reliable detector performance in safety-critical environments.
The system supports both routine bump checks and full calibrations, making it suitable for structured maintenance regimes and regulatory compliance programmes. By ensuring detectors are checked frequently and consistently, it helps maintain confidence that front-line instruments are ready for service whenever required.
High Throughput and Reduced Downtime
The Galaxy GX2 is optimised for busy workshops, depots, and central safety hubs where many detectors pass through each day. Its expandable architecture allows a bank to accommodate up to ten test stations, enabling simultaneous testing of multiple instruments. This high-throughput capability reduces bottlenecks, shortens wait times, and keeps workers in the field rather than waiting for equipment to be processed.
Integrated charging for compatible ALTAIR detectors, together with optional multi-way charger configurations, allows instruments to be tested and charged in the same dock. Detectors can be left to run through automated routines while operators focus on other tasks, returning to fully tested and, where configured, fully charged devices. Fast test times further minimise downtime during intensive periods such as turnarounds, shutdowns, emergency response preparation, and large maintenance campaigns.
Fleet-Wide Visibility and Audit-Ready Records
When connected to MSA Link™ Pro Software, the Galaxy GX2 serves as a centralised data hub for the entire ALTAIR fleet. The system provides total data access and control for connected detectors, enabling detailed test and exposure reporting. Records can be collected, stored, printed, and exported, supporting audit-ready traceability of every bump test and calibration event.
Software functionality includes gas exposure email alerts, direct data input, live data filtering, and query tools to support deeper analysis. A dashboard overview delivers fleet-wide visibility, helping safety teams identify instruments that need attention, confirm compliance status, and implement proactive gas-exposure monitoring strategies. This shifts gas detector maintenance from a reactive activity to a managed, data-driven process.
Intuitive Operation with Minimal Training
The Galaxy GX2 is designed for straightforward, low-touch operation. A colour touch screen supports easy setup, configuration, and viewing of test information, aided by large buttons, arrow keys, and clear navigation. At-a-glance indicators show test pass/fail, charging progress, system readiness, and gas-supply status, so users can quickly assess whether instruments are fit for deployment.
On-screen messages and LED indicators reinforce system status, while clear pop-up test results at the end of each cycle reduce ambiguity. Visual alerts for low calibration gas volume and cylinder expiration simplify gas management and help maintain continuous compliance. Eighteen-language support on both the test stand and MSA Link Pro Software facilitates global rollout and reduces training requirements across diverse workforces.
Scalable, Rugged Platform for Central Safety Hubs
The MSA Galaxy GX2 Calibration Unit is a fixed, industrial-grade test station intended for central locations rather than portable use. Its construction is suitable for demanding applications across sectors such as construction, general industry, oil and gas, utilities, mining, emergency response, firefighting, welding, confined space entry, and plant maintenance. The unit is non-hazardous and non-temperature-sensitive, making it appropriate for typical indoor industrial environments and safety workshops.
Multiple configuration options, including 1-valve and 4-valve variants and a wide range of part numbers tailored to different ALTAIR models and charging arrangements, allow alignment with specific gas setups and fleet mixes. The modular system architecture supports banks of up to ten test stations, with cylinder holder accessories for orderly mounting and management of calibration gas. Regional charger options, such as North American power configurations, support consistent deployment across sites.
Lower Cost of Ownership and Stronger Safety Culture
The Galaxy GX2 is optimised for use with MSA XCell® Sensors and is designed to reduce overall cost of ownership by supporting efficient, repeatable maintenance routines. Automated workflows and clear visual feedback reduce reliance on specialist calibration expertise, helping to shorten service windows and limit manual handling of detectors.
By simplifying regular bump testing and calibration, the system encourages consistent use of best practice, supports advanced maintenance schedules, and helps ensure continuous detector readiness. Comprehensive documentation, including datasheets, operating manuals, quick start guides, and technical literature on the importance of bump testing, further supports integration into existing safety workflows. The result is a dedicated, scalable calibration platform that underpins reliable gas detection performance and strengthens safety culture across the organisation.
