A new microprocessor-based meter made alcohol determination simple. Hanna HI 83540 alcohol analyzer uses a patented conductimetric known addition procedure that allows wine makers to accurately determine alcohol concentration in less than 5 minutes. The basis for this invention is that the changes of electric conductivity of a wine after the addition depends on the amount of alcohol. The complex software of the instrument performs all the necessary calculation and adjustments, providing the user with a direct readout of alcohol in % volume on the graphic LCD. For sweet wine measurement, the meter has a built-in algorithm for sugar content compensation. There are three types of sugar content compensation: Fixed Sugar Compensation, Type Sugar Compensation and Sugar Content Compensation. Users can configure their desired sugar compensation in the setup menu and the alcohol content measurement will be made using the selected sugar content compensation algorithm.
