This manual provides you with the necessary information for the correct use of the HI 84432 Titrimetric Acidity Minititrator & pH Meter for Fruit Juices.
The HI 84432 is an easy-to-use instrument designed for the rapid and accurate analysis of Total Titratable Acidity in fruit juices. It features a dedicated HELP key, a simple user interface, and a built-in algorithm to analyze pH responses for precise endpoint detection. The device automatically starts pump operation and titrates the sample to the end point when the START key is pressed.
| Titratable Acidity Range (Low) | g/100 ml as citric acid: + 0.20 - 1.20% CA |
|---|---|
| pH Range | -2.0 to 16.0 pH |
| pH Accuracy | + 0.01 pH |
| Temperature Range | -20.0 to 120.0 °C |
| Pump Debit | 0.5 ml/min |
The instrument determines the acidity by titrating until the end point at 8.2 pH is reached.
The pump calibration procedure should be performed a minimum of daily to maintain high precision.
The instrument is warranted for two years against defects in workmanship and materials.
