The Volumetric Karl Fischer Titrator
The Volumetric Karl Fischer Titrator by Hanna Instruments HI903 measures within 100 ppm up to 100 % water content. The titrator meets requirements for volumetric determination of higher water contents (e.g. ASTM D 4377) in crude oil, liquid petroleum products, biofuels and non-hydrocarbon organic compounds - alcohols, aldehydes, ketones, chlorinated solvents.
The Titrator HI903 combines a highly accurate dosing system with a design for optimal reaction speed and sophisticated relative drift evaluation.
Flexible and accurate endpoint determination: Selectable detection principle - relative drift, absolute drift or stable mV.
Due to the stable conditions in the titration vessel and the dynamic dosing of the titration reagent, the HI903 titrator can also be used for sensitive determination of low water concentrations.
