Product Description
The HI933 is an automatic volumetric Karl Fischer titrator with high accuracy, great !exibility and repeatability. The titrator is designed to perform titrations for a variety of sample
types/matrices, allowing the user to obtain both good results and high-speed analysis. The HI933 analyzes for water content ranging from 100 ppm to 100%. This powerful titrator automatically dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphing.

¦ Small footprint, requires minimal bench space
¦ Casing made with strong, chemically resistant plastic
¦ Powerful built-in algorithms for termination criteria based on fixed mV endpoint or absolute/relative drift
¦ Titrant standardization and sample analysis averaging
¦ Minimized water vapor entry with the Sealed Solvent System
¦ Balance interface for automatic weighing
¦ Support for 100 titration methods
¦ User-customizable reports
¦ Clearly displayed warning and error messages

Dynamic Titrant Dosing - The dynamic dosing feature allows for timely and accurate titration results by relating the titrant volume dosed to the mV response from the titration reaction. This provides for larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.
Drift Rate Compensation - The HI933 automatically adjusts the titration calculation to account for the e$ects of any ambient humidity entering the titration cell. This provides a more accurate result by correcting for water not present in the actual sample.
Titration Results Averaging - Successive results from a titration method may be averaged with recording of the standard deviation.
Titrant Recordkeeping - The HI933's titrant database can store information for up to 20 titrants. The database may be programmed to remind a user when to standardize their titrant, reducing error in analysis.
Selectable Endpoint Criteria - The HI933 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates.
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.
