Aquacounter® AQV-300 Coulometric Karl Fischer Titrator

The Aquacounter® AQV-300 is a compact volumetric Karl Fischer titrator for routine moisture measurement where bench space and ease of operation matter. It uses continuous titrant addition with intermittent addition near the endpoint, plus AC polarization potentiometric detection, to measure 0.1 to 500 mg H2O (10 ppm to 100%). The 10 mL buret, automatic ceramic-lapping valve switching, four titration-parameter files, and 20-result memory support repeatable daily testing with easy review, recalculation, and statistical analysis.
