AD Systems has developed a portable / on-site / on-board fully automated instrument for stability and compatibility testing of heavy fuel oil.

On board a vessel, a good way to measure the compatibility of marine fuels, including residual and distillate fuels is the ASTM D4740 spot test.

This patented portable device – ST10 is a complete automation of the ASTM D4740 method.

All the phases of the test are grouped in a suitcase, the conditioning of the samples, the preparation of the spot, its drying and the automatic rating by camera and associated software.

The only phases under the load of the operator are the sampling and the deposition of the drop with the aid of a micropipette supplied with the equipment.

As a result, the apparatus can be used anywhere by untrained persons whenever power is available.

The results are stored in a built-in result database. The image of the spot is memorized at the time the spot is rated. The ST10 ensures perfect traceability of the test.

• A complete automated system self-contained in a carrying case
• Multi-applications instrument, lab, on-site, on-board
• Standard test method used by conventional laboratories.
• Fully automated, no training or analytical knowledge required
• Removes subjectivity
• Prevent sludge deposits, failure of fuel handling systems and costly combustion related engine damage.
• No solvents
• Quick and reliable determination.
• Designed for both on-board use and lab use.
• Full traceability with built-in database
