The HI 84435 is an easy to use microprocessor-based automatic mini titrator and pH meter designed for quick and accurate analysis of titratable acidity in mustard. By eliminating subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions from the measurement, the HI 84435 makes titratable acidity analysis precise. This instrument will quickly become a valuable tool for mustard analysis.

A clear and intuitive user interface allows users to navigate the HI 84435’s menus and functions quickly. A HELP key located on the keypad aids in set-up, calibration status and troubleshooting.

Simply weigh the sample, dilute with water and press start. The HI 84435 automatically stirs the sample, starts pumps operation and titrates the sample to the endpoint.

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.

Titratable acidity determination is instantaneously displayed in the selected measurement unit on the display. The instrument is then immediately ready for the next analysis .

The HI 84435 employs a simple peristaltic pump to ensure the best accuracy and repeatability in measurements. To ensure the most consistent results, pump calibrations can be performed with the provided HANNA standard.
