HI 84102 is specifically designed to determine Total Titratable Acidity for wine analysis. This precision instrument is an economical and easy to use microprocessor-based automatic titrator that benefits from HANNA's years of experience as a manufacturer of analytical instruments. Titrations are driven by a simple and accurate peristaltic pump that is engineered to provide the best performance and repeatability possible. Hanna standards are provided to calibrate the pump and assure optimum instrument accuracy. Contained in this unit is a pre-programmed analysis method specifically designed for Total Acidity measurements in wine. A built-in powerful and effective algorithm analyses the shape of the pH electrode response and determines the reaction completion. The HI 84102 is equipped with a simple and effective interface where analysis and all calculations are automated and results are conveniently displayed on the readout LCD screen.
