Abstract

PURPOSE:To rationally store the same memory as data of a temperature change of a sample and to enable to perform a simultaneous measurement of a heat dispersion rate and a sepecific heat, by changing a distance between samplings corresponding to a measuring purpose. CONSTITUTION:A laser source 1 irradiates a sample 4 in a sample room 3 via a divider 2 with the output which is also supplied to a photo sensor 8. Outputs of a thermocouple 5 at the back of the sample 4 and an infrared detector 7 are slectively inputted to an amplifier 18 via preamplifiers 9, 10, and a switch 20, and the output of the photo sensor 8 is inputted to an integrator 13 and a rise detector 12 via an amplifier 11. Through the detecting output of the detector 12, a controller 14 transmits an output of a high-frequency sampling only during a period of time set by a setter 35, and after the time has elasped, it transmits an output of a low-frequency sampling, a memory 15 stores a sampling data. A computing circuit 16 computes a heat dispersion rate from an initial data, and computes a specific heat from a low-frequency sampling data and the output of the integrator 13.
