The HI84529 is an easy to use, fast and affordable automatic mini titrator designed for testing titratable acidity levels in dairy products. Based on an acid-base titration method, this mini titrator uses an optimized pre-programmed method of analysis with a powerful algorithm that determines the completion of the titration reaction by the use of a specialized foodcare pH electrode.

• Piston driven pump for accurate dynamic dosing
• Complete with anti-clogging reference electrode
• Pre-standardized titrant and pre-measured reagents

The HI84529 uses methods based on AOAC International and Standard Methods for the Examination of Dairy Products. Both of these methods report titratable acidity as % lactic acid and a conversion factor is used to convert the results to the other available units. The HI84529 can be customized to meet the needs of any dairy analysis lab.
