10128649 — MSA Altair 5X 6-Gas Detector with PID
The MSA Altair 5X is MSA Safety's most sophisticated portable multi-gas detector, extending the proven Altair platform to simultaneously monitor up to six gas channels including LEL, O₂, CO, H₂S, and an optional photoionisation detector (PID) for volatile organic compounds (VOCs) — the configuration specified for complex confined space entries and hazardous material response operations at ARAMCO refineries and petrochemical complexes where hydrocarbon vapour assessment beyond simple LEL is required. The addition of PID detection — sensitive to benzene, toluene, xylene, and hundreds of other VOCs at parts-per-billion concentrations — transforms the Altair 5X from a routine gas monitor into a comprehensive atmospheric hazard characterisation instrument, enabling industrial hygienists and H&S professionals to comply with ARAMCO's more stringent BTEX exposure monitoring requirements.
The instrument incorporates MSA's PID/LEL cross-interference compensation algorithm, which automatically applies correction factors when both sensors are active, preventing the false LEL alarms that occur in competing instruments when VOC concentrations affect the catalytic bead sensor's response. This technical refinement is particularly relevant at tank cleaning and turnaround operations at ARAMCO crude oil storage facilities and SABIC aromatic plants where mixed hydrocarbon atmospheres are the norm rather than the exception. The Altair 5X also features MSA's patented Motion Alert and Man Down alarm functions — if the instrument remains stationary for a user-defined period or tips horizontal, it escalates to a full-volume emergency alarm, providing a critical safeguard for lone worker operations in remote process areas.
ARAMCO HSE departments at Dhahran, Abqaiq, and Ras Tanura use the Altair 5X as the standard instrument for turnaround atmospheric monitoring teams, tank farm entry operations, and industrial hygiene sampling programmes. SABIC and SADAF safety departments issue the Altair 5X to personnel entering heat exchangers, distillation columns, and storage vessels during plant shutdowns where complex mixed-atmosphere risk profiles require PID monitoring in addition to standard confined space gases. The instrument's five-year XCell sensor warranty on CO and H₂S channels, combined with the low PID lamp replacement cost, reduces the total fleet ownership cost compared to competing multi-gas instruments.
Razz Middle East stocks the Altair 5X in standard configurations with and without PID module, along with replacement PID lamps (10.6 eV standard and 11.7 eV high-sensitivity) and isobutylene calibration gas standards. We provide instrument fleet procurement support, sensor replacement kits, and GALAXY GX2 integration services to HSE departments and EPC contractors across the GCC.

Key Features & Benefits
- PID sensor with 10.6 eV or 11.7 eV lamp option detects VOCs including benzene, toluene, and xylene at ppb concentrations, enabling BTEX exposure monitoring compliance at ARAMCO refinery and petrochemical confined space operations.
- MSA-patented PID/LEL cross-interference compensation algorithm prevents false LEL alarms in mixed hydrocarbon atmospheres common at tank cleaning, crude oil storage entries, and aromatic plant turnaround operations.
- Man Down and Motion Alert alarm functions escalate to full-volume emergency alert if the instrument is stationary for a set period or tips horizontal, providing critical lone worker protection in remote process unit areas.
- 5-year XCell sensor warranty for CO and H₂S channels (the longest in the portable gas detection industry) reduces total fleet cost of ownership for large HSE instrument programmes managing hundreds of units.
- Simultaneous 6-channel monitoring in a single compact instrument eliminates the need to carry multiple single-gas monitors, reducing worker load and HSE record-keeping complexity during confined space entries.
- GALAXY GX2 compatibility with automated bump test and calibration records ensures instrument fleet compliance is documented automatically, supporting ARAMCO and SABIC HSE audit trail requirements.
Industrial Applications in Saudi Arabia
- Complex confined space entries at ARAMCO crude oil storage tank farms and SABIC aromatic plants, where PID monitoring for benzene and BTEX compounds is required in addition to standard four-gas confined space monitoring.
- Plant turnaround atmospheric monitoring programmes at ARAMCO Ras Tanura refinery and SABIC Jubail plants, where industrial hygienists use PID data to assess hydrocarbon vapour exposures against ARAMCO occupational exposure limits.
- Hazardous material spill response operations at petrochemical and refinery facilities, where the Altair 5X enables first responders to characterise unknown VOC releases before committing teams to decontamination or containment tasks.
- Lone worker monitoring at remote pump stations and pipeline inspection tasks across ARAMCO's pipeline network, where the Man Down alarm provides automatic emergency escalation if a worker loses consciousness or is incapacitated.
- Industrial hygiene sampling at SABIC, SADAF, and SIIG facilities in Jubail Industrial City, where occupational health programmes require documented VOC exposure measurements for regulatory compliance and worker health surveillance.
