PRELIMINARY EXAMINATION

The

HI 84500 is a low-cost, easy to use, microprocessor-based automatic titrator that benefits

from Hanna’s years of experience as a manufacturer of analytical instrumentation.
The instrument incorporates a simple and reliable dosing pump which ensures high dosing
reproducibility. Pump calibrations, performed with the provided Hanna reagents, assure the
accuracy of the instrument.
The instrument comes with a preprogrammed method for Free and Total Sulfur Dioxide
measurements in wine. The instrument uses a powerful algorithm which analyzes the shape of
the electrode response in order to determine when the titration has reached completion.
The

HI 84500 provides a simple user interface. By simply pressing the Start key in Titration

mode, the instrument will automatically titrate the sample to the equivalence point and the
results are immediately displayed in ppm. Another titration can be started immediately by
pressing

Restart.
