Marine Instrumentation Gases are specialized gases used for calibrating and operating marine sensors and analyzers. Gas Systems in marine applications ensure safe storage, distribution, and delivery of these gases onboard vessels. They are critical for maintaining accuracy in environmental monitoring and safety systems.

Size: Typically available in cylinders ranging from 1 liter to 50 liters, with larger systems for industrial applications.

Grade: High-purity grades (99.999% or higher) for analytical instruments, industrial grades (99.5%+) for general use.

Viscosity: Dependent on gas type (e.g., helium has low viscosity, while sulfur hexafluoride is higher).

Buoyancy: Varies by gas density (e.g., helium is lighter than air, argon is heavier).

Material: Cylinders made of stainless steel or aluminum; seals and valves use PTFE, Viton, or other corrosion-resistant materials.

Pressure: Standard fills at 200-300 bar, with high-pressure systems up to 450 bar.

Temperature Range: Operational from -40°C to +60°C, depending on gas and system design.

Regulatory Compliance: Meets ISO, SOLAS, and IMO standards for marine safety.

Gas Types: Includes calibration gases (e.g., zero air, span gas), carrier gases (e.g., nitrogen, helium), and specialty gases (e.g., CO2, methane).

System Components: Manifolds, regulators, pressure relief valves, and leak detection systems.
