10116924 — MSA Altair 4X 4-Gas Portable Detector LEL/O2/CO/H2S
The MSA Altair 4X is MSA Safety's most rugged four-gas portable detector, simultaneously monitoring lower explosive limit (LEL), oxygen (O₂), carbon monoxide (CO), and hydrogen sulphide (H₂S) — the four gases mandated in confined space entry permits and hot work permits across every ARAMCO facility in the Kingdom. The instrument is built around MSA's XCell sensor technology, which delivers the industry's longest sensor lifespan at 4 years for the electrochemical CO and H₂S cells, reducing the total cost of ownership versus competing instruments that require annual sensor replacement at Dhahran, Abqaiq, and Ras Tanura field operations where maintenance overhead on instrument fleets is directly tracked by HSE KPI reporting.
The Altair 4X carries the IECEx and ATEX Zone 0/1/2 certifications required for use in explosive atmospheres at oil and gas processing facilities, LNG terminals, and refinery process units. Its IP68 ingress protection rating to 1-metre depth makes it drop-proof and washdown-resistant in field use — a meaningful durability advantage in the demanding outdoor environment of Eastern Province oil fields where instruments are handled by operations and maintenance crews across multiple shifts. The instrument survives a 2-metre drop test per IEC 62133 without damage or sensor drift, a specification that directly reduces annual instrument replacement costs for large fleet users such as ARAMCO HSE departments that manage hundreds of instruments across their Dhahran, Abqaiq, Ras Tanura, and Khurais operations.
In Saudi Aramco's confined space entry procedures, the Altair 4X meets the instrument specification requirements set out in ARAMCO GI-0002.100 (Confined Space Entry) and GI-0007.025 (Hot Work Permit). ARAMCO-approved laboratories in Dhahran and Abqaiq use the MSA GALAXY GX2 automated test system (a companion product also available from Razz Middle East) to manage fleet bump testing and calibration of Altair 4X instruments, with automated records uploaded to ARAMCO's HSE management system. This closed-loop calibration workflow is also adopted by SABIC, SADAF, and YANBU Aramco Refinery Company (YASREF) HSE departments for their portable gas detection fleets.
Razz Middle East is an authorised MSA Safety distributor for Saudi Arabia, maintaining stock of Altair 4X instruments, XCell replacement sensors, and associated calibration gas cylinders. Our team supports instrument fleet procurement for HSE departments, EPC contractors, and construction companies operating under ARAMCO and SABIC worksite safety requirements, with technical support for sensor replacement, bump test procedures, and GALAXY GX2 integration across all major Saudi industrial centres.

Key Features & Benefits
- XCell sensor technology provides 4-year electrochemical sensor life for CO and H₂S — the longest warranty in the portable gas detection category — reducing annual fleet calibration and sensor replacement costs for large ARAMCO HSE instrument programmes.
- Simultaneous four-gas monitoring (LEL/O₂/CO/H₂S) in a single compact instrument satisfies ARAMCO confined space entry and hot work permit requirements without multiple instrument carry.
- IECEx/ATEX Zone 0/1/2 dual certification covers the full range of explosive atmosphere classifications encountered in Saudi oil and gas production, refinery, and petrochemical facilities.
- IP68 rating (1 m, 1 hour) and 2-metre drop resistance per IEC 62133 deliver field durability that reduces annual instrument replacement costs in demanding multi-shift outdoor operations.
- 95 dB audible alarm, high-visibility LED array, and vibrating motor alarm operate simultaneously, ensuring gas alert awareness even in high-noise environments such as compressor stations and drilling sites.
- Compatible with MSA GALAXY GX2 automated test station for scheduled bump testing and calibration with automatic record-keeping, supporting ARAMCO and SABIC HSE fleet management compliance workflows.
Industrial Applications in Saudi Arabia
- Confined space entry atmospheric testing at all Saudi Aramco upstream, midstream, and downstream facilities under GI-0002.100, where four-gas monitoring is mandatory before entry permit is issued.
- Hot work permit atmospheric verification at ARAMCO and SABIC process plants, refineries, and tank farms, where continuous LEL monitoring during welding and cutting operations is required by GI-0007.025.
- Emergency Response Team (ERT) personal gas monitoring at ARAMCO and SABIC facilities in Dhahran, Abqaiq, Jubail, and Ras Tanura, where first responders require rugged reliable instruments in developing incident scenarios.
- Routine atmosphere sampling by operations and maintenance personnel at gas processing plants and LNG facilities across the Kingdom, where IECEx Zone 0 certification is required for instrument use in classified hazardous areas.
- Construction site safety monitoring at NEOM and Red Sea Project for contractors executing underground utility work, pipe-laying, and confined space civil construction in areas where gas ingress risk is assessed.
