GENERAL DESCRIPTION
The HI 84502 is a low-cost, easy to use, microprocessor-based automatic titrator that benefits from
Hanna’s years of experience as manufacturer of analytical instruments.
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 Total Titratable Acidity measurements in
wine.
The
HI 84502 performs the analysis and all the necessary calculations, with a simple and effective
user interface.
By simply pressing the
Start key in Titrator mode, the instrument will automatically titrate the
sample to the end point. The current pH and temperature are continuously displayed during titration
process. The result is immediately displayed in g/L, then the instrument is ready for another
titration by pressing the
Restart key.
A dedicated HELP key aids in setup, calibration, status and troubleshooting.
Other features:
• pH meter / mV meter
• Stir speed control
• Graphic mode to display the titration data
• Data can be stored using the log feature and then exported to a USB stick or
transferred to a PC using the USB connection
• Log on demand for up to 400 samples (200 for mV/pH measurements; 200 for
titration results)
• GLP feature, to view calibration data for pH electrode and pump
