Hanna - Model 84432 -Digital Automatic Minititrator and pH Meter
The HI 84432 digital automatic minititrator 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 accurate, repeatable results with no 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 end point. This instrument employs a powerful and effective 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 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.
