Abstract The main features of the pulse transient method are presented. The method gives the specific heat c and thermal diffusivity a for a single measurement, while thermal conductivity λ is calculated according to λ=caρ, where ρ is the density. The pulse transient method is a dynamic method based on the measurement of the temperature response to a heat pulse produced within a specimen. An apparatus operating in the temperature range from −40 to 100°C is described. Errors are discussed. The thermophysical properties of a CsPbCl3 single crystal are determined using the pulse transient method for a temperature range between 10 and 65°C in the controlled heating and cooling regimes. The data show anomalies in the thermophysical properties around the phase transition temperature at 47°C. Discrepancies in comparison with previously published data are discussed.
