PRELIMINARY EXAMINATION
The HI 84442 is an easy to use microprocessor-based automatic minititrator and pH meter designed
for rapid and accurate analysis of total very low alkalinity in water. By eliminating subjective factors
including color indicators, errors in mathematical calculations or erratic titrant additions from the
measurement, the HI 84442 makes Total Titratable alkalinity analysis precisely. This will quickly
become a valuable alkalinity analysis tool of waters.
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 84442 automatically starts pump operation and titrates
the sample to the end point. The HI 84442 has a simple and accurate peristaltic pump to ensure the
best accuracy and repeatability. By performing pump calibration with the Hanna standard provided,
