Aquamax KF Plus
Reliable Water Content Determination
Downloads
Product description
The Aquamax KF Plus series is designed for accurate water content determination according to international standards (ASTM, API, BS, DIN, EI/IP, EN, IEC, ISO), combining the Karl Fischer method with precise coulometry.
Compact, robust, and user-friendly, the Aquamax KF Plus and Aquamax KF Portable titrators feature a tough measuring vessel, intuitive ‘press-go’ operation, and a built-in printer for immediate documentation.
Thanks to their small footprint and fully enclosed components, these instruments save valuable lab space and are easy to transport.
The integrated battery ensures flexible operation outside the lab — ideal for mobile labs, fieldwork, or unstable power environments.
Key Features:
- Water determination according to international standards
- Tough and durable measuring system
- Compact design with enclosed parts for portability
- Built-in battery for mobile or remote use
- Easy operation with a press-go keypad and integrated printer

Gas tight sampling syringes
Each Aquamax KF Plus/Portable is supplied with a white lettered gas tight sampling syringe and luer needle which has been designed specifically for accurate sampling of oils and fuels.
Water check
The µg check button allows the operator to simply press go, inject 1 µL or maybe 10 µL 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 to the pre-programmed setting.

Tough measuring vessel
The unique LDC glassware design is by far the easiest to use and 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.

Where do you need an Aquamax KF
From raw materials to finished products, to preventive maintenance programs, you will find Aquamax KF in the labs, the back of mobile rigs and even on-line as part of an industrial process. If you are testing any of the following processes and samples you may need an Aquamax KF instrument to test you water content!
- Exploration and Production of Crude Oil and Natural Gases
- Refining of petroleum products like Bitumen, Fuel Oil, Lubricating Oils, Waxes, Polishes, Diesel Fuel, Jet Fuel, Paraffin, Petrochemicals, Gasoline and Bottled Gas (LPG)
- Pipeline & Transportation of oils, fuels and petrochemicals
- Biofuels
- Plastic & polymer components
- Pharmaceutical products
- Extracts like cannabis oil and vaping fluids
