HANNA HI84502-01 Mini-Titrator for Measuring Titratable Acidity in Wine
The HI84502 is a simple, fast, and affordable automatic mini titrator designed for testing total acidity levels in wine. Based on an acid-base titration method, this mini titrator uses an optimized preprogrammed method of analysis with a powerful algorithm that determines the completion of the titration reaction by the use of a specialized wine pH electrode.
Analysis for titratable acidity with the HI84502 is not selective for acids of similar strength. In this method, a base of known concentration is used to understand the overall acid content of a sample and express it as the main acid present in wine, tartaric acid.
The HI84502 incorporates a precision piston style dosing pump that adjusts the volume of dosing dynamically based on the voltage changed. This dosing system reduces the amount of time required for the titration while providing for a highly accurate determination of the amount of titrant used.
This mini titrator is supplied complete with all the materials necessary to perform low and high range measurements of total acidity. All chemicals are premixed and prepackaged including standardized titrants, reagents and pump calibration solution. There is no need for volumetric glassware or analytical balances.
