Karl Fisher Titrators
Volumetric Karl Fischer Titrator Model AQV-2200S  

AQUACOUNTER’s new AQV-2200 full-featured titrator is the perfect choice for a very wide range from approximately 100 ppm to 100% water content with its maximum capability for automation and future upgrade capability.

Suitable for :100ppm  ~ 100% H2O

  Single channel: AQ-2200 w/ standard titration cell  



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 is easy to replace with fresh solvent for next measurement.

Two KF Channels

Two KF channels can run in parallel!

Combining one additional KF station with either a volumetric or coulometric channel enables two different measurements to be performed at the same time. Save time with this 2 channel, flexible configuration.

Twin Burets

Additional burets and buret-heads!

Compact additional burets and light snap buret heads are useful for quick KF reagent exchange or back titration applications.

Control Panel

Intuitive control panel display!

Current status, data and function keys are displayed on a colorful and large color touch screen. All helpful and necessary information is always in your hands!


Browse data by PC on a LAN connection!

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


USB flash memory port!

Save & load parameters and results via USB flash memory.
