The HI 84432 digital automatic mini titrator and pH meter is designed for quick 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 provides quick and accurate, repeatable results without guesswork. A clear and intuitive user interface allows users to navigate the HI 84432’ s menus and functions quickly. A HELP key located on the keypad 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 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 titratable acidity determination is instantaneously displayed in selected measurement units on the large dot matrix display. The instrument is immediately ready for the next analysis. The HI 84432 has a simple and accurate peristaltic pump to ensure the best accuracy and repeatability. To ensure instrument accuracy, perform a pump calibration with the provided HANNA standard. Why This Instrument is So Important... The measurement of titratable acidity in fruit juices measures the concentration of titratable hydrogen ions contained in the fruit juice samples by neutralization with strong base solution to a 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 base solutions, the titratable acidity is usually expressed as a percentage ( mass/ volume) of the predominant acid: Citric acid is present in many fruit species. Tartaric acid is essentially found in grapes. Malic acid is present in many fruit species, sometimes together with citric acid or tartaric acid in unripe grapes. The HI 84432 Mini Titrator uses a method based on the Official Methods of Analysis of AOAC International. The fruit juice is titrated with a sodium hydroxide solution until the end point at 8.2 pH is reached ( determined by potentiometric method) . Additionally the HI 84432 has a built-in pH meter for pH measurement ( electrode and meter must be calibrated) .
