The MSA ALTAIR® 4X is a SOLAS/MED-approved professional four-gas detector designed for use in commercial maritime, offshore and other hazardous working environments. This specific configuration provides simultaneous monitoring of combustible gases (LEL), oxygen (O₂), carbon monoxide (CO) and hydrogen sulfide (H₂S), helping users identify dangerous atmospheric conditions quickly and reliably.
SOLAS/MED approval makes the ALTAIR 4X particularly suitable for regulated maritime applications, including commercial vessels and offshore operations where certified safety equipment is required. The approval is a key feature of this specific configuration and makes it an appropriate choice for professional maritime gas detection.
The detector uses MSA XCell® sensor technology to provide fast response times and long sensor service life. The sensors can provide up to four years of operating life, helping reduce maintenance requirements and the total cost of ownership. The instrument also requires less calibration gas than many conventional detectors, helping to reduce operating costs.
The ALTAIR 4X provides up to 24 hours of continuous operating time, making it suitable for extended shifts and demanding working schedules. A high-contrast display provides clear gas readings, while large buttons make the instrument straightforward to operate. Visual, audible and vibrating alarms provide immediate warning when dangerous gas concentrations are detected.
Designed for demanding professional use, the detector features a durable ribbed rubber housing that provides a secure grip and helps protect the instrument against impacts. The phosphorescent housing improves visibility in low-light conditions, making the detector easier to locate and read in dark working environments.
Additional personal safety functions include MotionAlert™, which can automatically signal when the user becomes immobile, and InstantAlert™, which allows the wearer to manually activate an alarm in an emergency situation.
The detector also includes datalogging functionality, allowing gas readings, alarms and other events to be recorded for later analysis and documentation. This can be particularly valuable for maritime operators, safety managers and organisations that require records of atmospheric monitoring.
The four-gas configuration detects:
- LEL – combustible gases
- O₂ – oxygen
- CO – carbon monoxide
- H₂S – hydrogen sulfide
The MSA ALTAIR 4X combines SOLAS/MED approval, four-gas detection, rugged construction, extended battery life and long-life sensors in a compact portable instrument. It is an excellent choice for commercial shipping, offshore operations, confined-space entry, firefighting, emergency response and industrial applications where certified gas detection is essential.
