Karl Fischer Coulometric Titrator HI934 Hanna Instruments For scientists and professionals who need exact water content determination from 1 ppm to 5%, our new generation of the Coulometric Karl Fischer Titrator is engineered to meet or exceed your technical requirements while delivering a lower cost of ownership. With cutting-edge features packed into a compact design, this titrator delivers accurate results and requires less space in the lab. Get accurate water content determination at the push of a button. Designed for the modern lab, this karl fischer titrator is the perfect fit for your testing environment.
Compact design will save space in the lab without compromising your results.
Durable heat and chemical resistant body.
Sealed solvent system helps to keep water out of the system, while giving you minimal exposure to the reagents.
Dynamic Titrant DosingThe titration speed feature allows for timely and accurate titration results by relating the amount of iodine generated to the mV response from the Karl Fischer reaction.
Drift Rate CompensationThe HI934 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.
Titration Results AveragingSuccessive results from a titration method may be averaged with recording of the standard deviation.
Selectable Endpoint CriteriaThe HI934 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 PreparationA 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.
Titration System
Precision Iodine Generation
Hanna’s dosing algorithm allows for an extremely small amount of iodine necessary for the Karl Fischer reaction to be generated electrolytically using a pulsed current up to 400 mA delivering titrant accurately and precisely.
Chemically Resistant Titration Vessel and Tubing
The glass titration cell and PTFE tubing is designed to withstand the harsh solvents and reagents involved in Karl Fischer reactions.
Sealed Solvent System
Ground glass joints completely seal the glass titration cell minimizing exposure to ambient humidity, keeping the system dry, and reducing reagent consumption while saving time between titrations. Solvent may be exchanged in a matter of seconds with a quick fitting adjustment.
Molecular Sieve Desiccant
High efficiency molecular sieve desiccant helps maintain low and stable drift rates within the titration cell while preventing the ingress of ambient humidity into the sealed solvent system.
Digital Built-in Stirrer
Automatic, integrated magnetic stirrer adjustable from 200-2000 RPM with optical feedback for automatic speed control.
Titrator Data & Reporting
Customizable Titration Reports
Each titration report is fully customizable so users can ensure they are storing and filing the appropriate data required for their application and procedures.
Flexible GLP Management
All necessary GLP (Good Laboratory Practice) information can be recorded with each sample including: sample identification, company and operator name, date, time, electrode ID codes, and calibration information.
Effortless Data Transfer
Data can easily be transferred to a USB flash drive or PC with the Hanna HI900PC application software. The USB port allows for the transfer of titration methods, titration reports, and software upgrades via USB flash drive.
