Abstract
History of DTA automation, mainly in Japan, is reviewed. In 1953-1955, automated DTA apparatuses had been assembled in three laboratories using U. S. made devices, Japanese devices and self- made devices. These attempts to make fully automated apparatuses were followed by commercialization, which is described in the other papers in this special issue. Beside these DTA apparatuses, an early automated apparatus of heating curve method by LeChatelier and other early automated DTA are also described with some automated thermobalances.
