Aquamax KF Portable – On-site ppm water content


Measuring and controlling the amount of water in oils and fuels is of considerable economic importance to the industrial community, particularly to the petroleum, fuel, used oils and electric power industries. Water content determination by Karl Fischer titration is no longer restricted to being used by a chemist in a laboratory – now the technique is used by, plant operators, tanker drivers, distribution/maintenance engineers and other non-laboratory personnel.

Karl Fischer titrations can now be performed in many different locations such as the tailgate of trucks, mobile laboratories, offshore installations, tankers, engineering workshops and dockside cabins.

The Aquamax KF Portable is simply a mobile version of the very successful Aquamax KF Plus.


Water check

The μg check button allows the operator to simply press go, inject 1μl or maybe 10μl of distilled water (as required by some ASTM methods) and verify if the instrument and reagent are working with in their required specification. The μg check overrides the programmed calculation and displays/prints out a report of the verification check. The coulometer then automatically reverts back to the pre-programmed setting.

Tough measuring vessel

The unique LDC glassware design is by far the easiest to use and also the most robust. The electrode locking system allows the joints to seal completely, without the use of grease or PTFE sleeves, and provides improved baseline stability. Hassle free assembly and disassembly.

Built in battery and built in printer for on-site use

The Aquamax KF Portable is a small, single foot print instrument with integrated printer, a built-in battery and carrying case allowing the field engineer to take the instrument complete with an assembled measuring vessel and ready for immediate use on arrival at destination.

Rugged case and tough measuring vessel make a real mobile Karl Fischer titrator

Results manager

This is a windows application that allows you to view and print sets of results created by the Aquamax KF itrator. It can download results directly from the instrument via a serial port connection, or open result files previously saved to disk. The Results Manager package contains all necessary cables, connections, installation cd and user manual.

For those who need to use the titrator outside of the laboratory, the removable flash drive (memory stick) will store all the results whilst you complete your on-site work. The USB flash drive can then be connected to a pc and results downloaded via Results Manager when returning to your work place.

To conform to ASTM, API, etc., methodologies, it is necessary to homogenise crude oil samples prior to analysis. The PRO25D is a powerful and versatile low cost digital homogenizer whilst the SB-1 model is a Silent Brushless Homogenizer which is maintenance free as it has no carbon brushes, so it runs cleaner and quieter.
