Titratable Acidity Mini Titrator and pH Meter for Vinegar

The HI 84434 is an easy to use automatic mini titrator and pH meter designed for the quick and accurate analysis of total titratable acidity in vinegar. By eliminating subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions from the measurement, the HI 84434 makes total titratable acidity analysis precise. This will quickly become a valuable analysis tool of vinegar.   
   
A clear and intuitive user interface allows users to navigate the HI 84434’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 84434 automatically starts pump operation and titrates the sample to the endpoint.   
   
The instrument employs a powerful and effective built-in 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 the selected measurement unit on the large display. The instrument is then immediately ready for the next analysis.   
   
The HI 84434 employs a simple peristaltic pump to ensure the best accuracy and repeatability in measurements. To ensure the most consistent results, pump calibrations can be performed with the provided HANNA standard.
