Water determination in oil samples by Aquamax KF PRO Oil (ASTM D 6304)

The Aquamax KF PRO Oil fulfils the requirements of the standard ASTM D 6304: Standard Test Method for Determination of Water in Petroleum Products, Lubricating 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. This unique ECH feature allows you to see all various types of bonded water, making the Aquamax KF Pro Oil the perfect tool in the R & D, Refining, Used Oil analysis laboratories and lubricant blending plants. Crude oils are also perfectly analysed as we have the ability to display both free and bonded water.

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, because its capacity can be used completely.


Water extraction of the samples at temperatures 35 °C up to 250 °C, e. g.:

  • Constant temperature
  • Individually set up temperature programs
  • Freely selectable temperature ramp
  • Time-controlled temperature programs for step-by-step heating
  • Type of result: µg, µg/L, mg/L, mg/kg, ppm, %, by using the formula generator
