Aquamax KF PRO Oil

The Aquamax KF PRO Oil fulfils the requirements of the standard ASTM D 6304: Standard Test Method for Determination of Water in Petroleum Products, Lubri-cating Oils, and Additives by Coulometric Karl Fischer Titration.

The Aquamax KF PRO Oil is the perfect instrument to measure ppm water in oils and fuels without the worry of interference side reactions caused by additives or sulphur/mercaptans. The unique "closed loop" principle means no additional carrier gas is necessary. Directly injecting the sample in to the oven means no blank value is required, making the Aquamax KF PRO Oil a truly accurate, trace level water in petroleum products titrator.
Learn more about your oils by using the temperature ramping program allowing you to see the various types of bonded water making the Aquamax KF PRO Oil a perfect R&D tool.

All Aquamax KF PRO Oil parts are totally enclosed making this system completely safe and robust for use in the demanding petroleum industry.

The ECH technique allows a very long reagent life capable of analysing over 1000 samples without changing or swapping reagent.
