概要

• 論文の詳細を見る

• We built as a trial an automatic measuring system of acid values of different varnishes, which can be used in a factory to decrease errors by a manual handling and simplify a titration work.<BR>A change in colour with phenolphthalein at the end point of titration is read out as a change of voltage and the total volume of titrant is converted into the voltage by the operating circuit.<BR>Acid values of benzoic acid, fatty acids, and alkyd varnishes were measured by our system and obtained results are more accurate than results by a manual method in the coefficient of variation.
