ABSTRACT:
A thermal analysis instrument which is equipped with a cooling mechanism and device for blowing a drying gas so that when low temperature are being measured moisture is prevented from condensing on the upper end surface of the heating furnace and on a cover that closes the inside of the heating furnace to thereby prevent deposition of frost. Where a robot mechanism is added to this thermal analysis instrument equipped with the cooling mechanism, it is not necessary to impose additional functions on the robot mechanism. The device for blowing a drying gas presents an annular passage mounted near the upper end surface of the heating furnace for blowing the drying gas against the upper end surface and the cover to thereby prevent the deposition of frost.
