Making sure you have the correct gas, exactly when and where you need it
A high-quality range of regulators designed for excellent performance and durability
Calibration gas ensures that gas detection instruments on vessels provide accurate readings of potentially hazardous gases such as oxygen (O2), hydrogen sulphide (H2S), or carbon monoxide (CO). This accuracy is critical for maintaining crew safety, avoiding false alarms, and complying with maritime safety regulations like SOLAS (Safety of Life at Sea).
Application on Vessels:
Gas detectors are used in confined spaces like engine rooms, cargo holds, and ballast tanks, where gas leaks or oxygen depletion can pose serious risks. Regular calibration ensures that these detectors function correctly to protect crew and cargo.
Gas detectors on vessels should generally be calibrated every 6 to 12 months, but more frequent calibration may be required depending on environmental conditions, the type of gases monitored, and the manufacturer’s recommendations. Regular bump tests should also be conducted between calibrations to verify proper functionality.

Application on Vessels:
On ships, gas detectors are exposed to harsh conditions like saltwater, temperature variations, and humidity. This makes regular calibration vital to ensure the detectors remain accurate and reliable, especially in critical areas like fuel storage or during tank entry.
Common calibration gases used on vessels include oxygen (O2) for ensuring breathable air levels, carbon monoxide (CO) for detecting engine exhaust leaks, hydrogen sulphide (H2S) for monitoring toxic gas emissions, and methane (CH4) for detecting combustible gas leaks. These gases are supplied in precise mixtures for accurate calibration of detection equipment.
Application on Vessels:
Calibration gases are used to test gas detectors in areas like cargo holds, lifeboat compartments, and machinery spaces. Correct calibration helps ensure these sensors can accurately detect dangerous gas levels before they reach hazardous concentrations, keeping both crew and cargo safe.
