The HI 84433 is an easy to use automatic mini titrator and pH meter designed for the rapid and accurate determination of formol number in wines or fruit juices. By eliminating subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions from the measurement, the HI 84433 makes formol number determination precise.
A clear and intuitive user interface allows users to navigate the HI 84433’s menus and functions quickly. A HELP key located on the keypad aids in set-up, calibration status and troubleshooting.
After an initial sample prep, the HI 84433 starts pump operation and titrates the sample to the endpoint. This instrument employs a powerful and effective algorithm to analyze the pH response to determine the exact pH endpoint, then uses this algorithm to make the necessary calculations.
The formol number determination is instantaneously displayed in selected measurement units on the large dot matrix display. The instrument is ready for the next analysis immediately.
The HI 84433 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.
The HI 84433 has two operating options:
