Hanna Instruments has developed a simple, fast and affordable mini automatic titrator designed for testing titratable acidity in fruit juice.
Compared to its predecessors, the HI 84532 mini titrator provides increased accuracy by improving the titrant delivery system and measuring ranges, according to Hanna Instruments.
It measures the concentration of titratable hydrogen ions contained in fruit juice samples by neutralisation with a strong base solution to a fixed pH as according to the official methods of analysis of AOAC International.
This value includes all the substances of an acidic nature in the fruit juice including free hydrogen ions, organic acids and acid salts.
The predominant acids in fruit depend on the type of fruit being tested and could include citric acid, tartaric acid and malic acid.
This mini titrator includes a pre-programmed analysis method for titratable acidity measurements in fruit juice. Automatic stirrer speed control maintains consistent stirring speed at approximately 600 rpm.
The graphic mode displays in-depth data on titration, which can then be stored using the log feature. The log on demand feature can store up to 400 samples (200 for titration results, 200 for pH/mV), and the GLP feature allows users to view calibration data for the titrator and pump.
In addition to performing titrations, the HI 84532 can be used as a pH meter for direct pH/mV measurements.
