​HI903-01 Volumetric Karl Fischer Titrator

Unlike other Karl Fischer titrators, the HI903 features an ultra-high precision dosing system and a specialized burette design for unmatched accuracy.
A Better Volumetric Karl Fischer Titrator Experience Our friendly technical consultants take pride in helping make your titrator selection easy – every step of the way. Our experts are here to guarantee you have a positive experience, from onsite installation and training to customization and continued support.

The HI 903 Karl Fischer Volumetric Titrator for moisture analysis combines an ultra-high precision titrant delivery system with optically regulated magnetic stirring, sophisticated endpoint determination, dynamic dosing and background drift correction algorithms. The HI 903 dispenses the titrant, detects the endpoint and performs all necessary calculations
automatically. It comes equipped with a solvent handling system to reduce cell conditioning time and can be connected directly to your laboratory balance via serial interface.
