PROBLEM TO BE SOLVED: To provide a thermocouple system for heating measurement having a temperature detecting and heating function, and a sample holding function in a thermocouple, and capable of improving a temperature control function, sample observation and data recording or the like. SOLUTION: This thermocouple system is provided with a heating measurement unit 1 constituted to electrify and heat the thermocouple 3 holding a sample 6 with a half-cycle rectangular wave by a heating electric power source part 23, while conducting alternately switching between the heating electric power source part 23 and a measuring part 24 by a heating measurement switching part 22, to digital-convert an analog temperature signal based on electromotive force from the thermocouple 3 in an A/D-conversion part 25 during the next half cycle, by the measuring part 24, to receive and control a converted digital temperature signal in a control part 21, to analog-convert the digital temperature signal in the control part 21 by a D/A-conversion part 26, and to receive an analog value to be temperature-controlled by a temperature regulation part 27, and a setting operation means 2 allowing various setting operations, and a melting state of the sample, a reaction of a molten body with a solid or the like can be easily and directly observe in a prescribed observation temperature, by the system.
