The HI84532 is a simple, fast, and affordable automatic mini titrator designed for testing the acidity of fruit juice. 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 glass body pH electrode.

• Piston driven pump for accurate dynamic dosing
• Complete with glass double junction pH electrode
• Pre-standardized titrant and pre-measured reagents
• Supplied with the HI1131B refillable, double junction, combination pH electrode
• Built-in stirrer is automatically maintained at a speed of 600 rpm, regardless of the viscosity of the solution being titrated

This mini titrator is supplied complete with all the materials necessary to perform low and high range measurements of titratable acidity in fruit juice. Results are displayed as % citric acid, tartaric acid and malic acid. All chemicals are premixed and prepackaged including standardized titrants, reagents and pump calibration solution. There is no need for volumetric glassware or analytical balances making titrations fast and easy to perform.
