Basic principles
Based on the principle of unstable thermal conductivity, the instrument is heated in the experimental material for a short time to make the temperature of the experimental material change. According to the characteristics of the change, the thermal storage coefficient, pekali kekonduksian haba, temperature conductivity coefficient and specific heat of the test material can be calculated by solving the differential equation of thermal conductivity.
