Titratable Acidity Mini Titrator & pH Meter for Fruit Juices
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.
The Titratable Acidity determination is instantaneously displayed in selected measurement units on the large dot matrix display. The instrument is ready for the next analysis immediately. Other features:>Log on demand up to 100 samples (50 for pH measurement; 50 for titration results) >GLP feature, to view last calibration data for pH electrode and pump > PC interface via USB connection
Titratable acidity of fruit juices measures the concentration of titratable hydrogen ions contained in the fruit juices samples, by neutralization with strong base solution at fixed pH. This value includes all the substances of an acidic nature in the fruit juice: free hydrogen ions, organic acids, acid salts and cathions.
Because the organic acid is the most acidic component of the fruit juices that react with strong bases solutions, the titratable acidity is usually expressed as g/L or g/100mL of the predominant acid contained:
g/100 mL as citric acid : 0.20 – 8.00% CA
g/100 mL as tartric acid : 0.23 – 9.30% TA
g/100 mL as malic acid : 0.21 – 8.30% MA
