AQUACOUNTER. AQV-2200S Karl Fischer Volumetric high-end titrator is the perfect choice for a very wide range from 100 ppm to 100% water content with its maximum capability for automation and future up-gradeability. An example of a 2 channel configuration is shown below. 


Economical & Eco-friendly small-volume cell!

Small-volume titration cell requires only 20mL of titration solvent for accurate measurements. Less reagent volume reduces waste and easy to replace with fresh solvent for the next measurement.

Two KF channels run in parallel -- Plug and Play!

Combining one additional KF station with either a volumetric or coulometric module enables two different measurements to be performed at the same time. With both a volumetric and coulometric channel, one can measure moisture over the entire range from 1ppm to 100% or double your sample throughput with 2 identical KF stations.

Additional burets and buret-heads!

Compact additional burets and easy, snap-on buret-heads are useful for quick KF reagent exchange or back titration applications.

Intuitive control panel display!

Current status, data and function keys are displayed on a colorful and large screen. Color touch screen is 7.5-inches wide. All helpful and necessary information is always at hand!

Browse data by PC on a LAN connection!

Result data with curves can be viewed on your PC internet browsing program without optional software.

Enhanced memory data capacity!

Save & load parameters and results via USB flash memory.

Built-in thermal printer!

Easy paper loading. High resolution, clear printout.
