The Aquamax® Karl Fischer Plus Titrator is a robust, high-precision instrument designed for the determination of trace water content using coulometric Karl Fischer titration. This advanced moisture analysis system is ideal for laboratories requiring accurate ppm-level moisture determination in samples such as oils, fuels, solvents, chemicals, and other liquids.

The instrument combines coulometric titration with the Karl Fischer method, delivering extremely sensitive and reliable water content measurements ranging from 1 ppm up to 100% water. Its simple “press-go” operation, integrated printer, and programmable methods make it an extremely user-friendly instrument suitable for routine laboratory testing as well as on-site analysis.

The compact and portable design, integrated battery, and removable data storage enable users to perform moisture analysis both inside and outside the laboratory, making the Aquamax KF Plus particularly useful for petroleum laboratories, chemical plants, food analysis labs, and research facilities.

Water Check Verification System

The Aquamax KF Plus includes a μg verification function allowing quick performance verification of the instrument and reagents.

The operator can inject a small volume of distilled water (e.g., 1 μL or 10 μL) to confirm that:

• The instrument is functioning correctly
• The Karl Fischer reagent is performing within specification

After the verification check, the system automatically returns to the programmed analytical method, ensuring uninterrupted workflow.

Tough Measuring Vessel Design

The instrument uses a Low Drift Cell (LDC) measuring vessel, specifically engineered for:

• Improved measurement stability
• Reduced baseline drift
• Easy assembly and cleaning
• No grease or PTFE sleeves required

The electrode locking system ensures tight sealing and reliable operation during titration.

Results Manager Software

The Results Manager software provides comprehensive data management:

• Download results directly from the titrator
• View and analyze test results
• Print detailed analytical reports
• Export measurement data for record keeping

The system can also store results on a USB flash drive for later analysis on a computer.

Measurement Principle

The Aquamax KF Plus uses coulometric Karl Fischer titration, one of the most sensitive techniques for water determination.

In this method:

• Water reacts with iodine generated electrochemically in the titration cell
• The reaction continues until all water in the sample is consumed
• The amount of iodine generated corresponds directly to the water content

This technique allows precise detection of trace moisture levels down to microgram quantities.
