Marine Fuel Quality & On-Board Assurance

Testing the fuel density, compatibility, and stability of delivered oil provides reassurance regarding oil quality and cost conformity. Whereas verification of stability and compatibility of different marine heavy fuel oils (high sulphur and low sulphur fuel oil) and marine gas oils (MGO) is regarded as an essential measure for ensuring continuous normal operation of the engine system.

These important oil parameters can be determined directly on-site with the help of the test device COMPA DENS CHECK in easy and quick test procedures.

Why Test Density & Compatibility On-Board?

• Commercial Verification: Fuel is paid by weight but delivered by volume. Precise density measurement ensures accurate mass conversion.

• Engine Protection: Incompatible fuel mixtures cause asphalt/sludge precipitation, clogging filters and risking main engine power loss.

Key Advantages & Operational Benefits

Engineered for maximum reliability and ease of use in harsh marine environments:

⚡ Quick & Adjustable Heating

Built-in controlled heating bath quickly reaches target temperatures (50 °C for density, 95 °C for compatibility), ensuring safe and consistent test conditions every time.

???? High Precision & Accuracy

Equipped with 4 specialized hydrometers (0.82 to 1.05 g/ml range), providing highly accurate density readings within ± 3% tolerance.

⏱️ Fast & Reliable Results

Determines oil density in just 2 minutes and fuel compatibility within 20 minutes, giving immediate "Go / No-Go" visual guidance before fuel transfer.

????️ Simple & Easy Handling

Designed specifically for shipboard operation, allowing non-trained crew members to execute precise ASTM D 4740-04 spot tests with ease.
