The test kit COMPA DENS CHECK is designed for regular monitoring of the fuel oil quality delivered on board a vessel and can be used for testing of three parameters: density, stability, and compatibility.

This video manual shows the detailed testing procedure of compatibility of different fuel oils, which is guided by ASTM D4740-04 (2014).

The availability of nearly immediate test results contributes to effective decision-making when the potential co-mingling of two fuels is under consideration.

Onboard compatibility testing with the COMPA DENS CHECK can be performed for different marine heavy fuel oils (high sulphur and low sulphur fuel oils) and marine gas oils (MGO).
