Coulometric Karl Fischer Titrator

Dynamic Titrant Dosing

• The dynamic titration speed allows for timely and accurate titration results by relating the amount of iodine generated to the mV response from the Karl Fischer reaction. This provides for a larger generation of iodine near the beginning of a titration and more precise pulses near the titration endpoint.

Selectable Endpoint Criteria

• The HI904 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates.

Drift Rate Compensation

• The HI904 Coulometric Karl Fischer Titrator automatically adjusts the titration calculation to account for the effects of any ambient humidity entering the titration cell. This provides a more accurate result by correcting for water not present in the actual sample.

Multistage Cell Preparation

• A pre-titration stage eliminates residual water present in the solvent and the cell, providing a reliable baseline start to analysis. Standby mode then keeps the solvent dry between titrations and when the titrator is not in use.
