PRELIMINARY EXAMINATION
The
HI 84432
is an easy to use microprocessor-based automatic minititrator and pH meter designed
for the rapid and accurate analysis of Total Titratable Acidity in fruit juices. By eliminating subjective
factors including color indicators, errors in mathematical calculations or erratic titrant additions from
the measurement, the
HI 84432
makes Total Titratable acidity analysis precisely. This will quickly
become a valuable acidity analysis tool of fruit juices.
The instrument benefits from Hanna’s many years of experience as manufacturer of quality analytical
instruments. A clear and well-designed user interface makes the instrument intuitive and simple to
use. A dedicated
HELP
key aids in set-up, calibration, status and troubleshooting.
By simply pressing the
START
key, the
HI 84432
automatically starts pump operation and titrates
the sample to the end point. The
HI 84432
has a simple and accurate peristaltic pump to ensure the
best accuracy and repeatability. By performing pump calibration with the Hanna standard provided,
the instrument accuracy is assured.
The instrument employs a powerful and effective built-in algorithm to analyze the pH response to
determine the exact pH endpoint, then uses this to make the necessary calculations.
