A twin conduction-type microcalorimeter (Rhesca CM-204-D1) has been improved especially on its agitation mechanism and ampoule-breaker. These mechanisms were simplified that the duration up to thermal equilibrium was shortened and the base line was stabilized. A simple digital data processing system controlled by the microcomputer MZ80K has been made for the data acquisition and calculation required. Heats of immersion of both rutile and anatase in water have been obtained as a function of sample weight and the results were 350 and 500 erg/(cm)^2 respectively, for the samples outgassed at 400℃ for 1 h in vacuo. Lower limit for heat-detection of this calorimeter system under conditions applied to the present case was 0.1-0.2 joule on the heat of immersion experiment.
