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.
