The HI84432 is an easy to use, automatic titrator and pH meter designed to give fast, accurate measurements while eliminating errors caused by color indicators or mistakes in calculations.

A simple yet accurate peristaltic pump as well as a powerful and effective algorithm are used to determine the exact pH endpoint and to make the necessary calculations which are displayed in selected measurements on the easy to read display. The intuitive user interface allows quick navigation of the menu and functions and the "help" button makes setup, calibration, storage and troubleshooting a breeze. Log and store up to 100 samples with time and date to be viewed later. If errors occur in the calibration or if the electrode is dirty or broken the problem is pinpointed and the appropriate message is displayed as well as a reminder when calibration is required or due.
