PURPOSE: An experiment apparatus for adjusting a temperature using a thermoelement is provided to increase a cooling speed and a heating speed inside the chamber constantly by mounting a fixed cooled thermoelement and a variable-type of thermoelement with the described spaces inside the chamber and varying the intensity and polarity of the direct voltage applied to the variable-type of thermoelement depending on a temperature difference. CONSTITUTION: In an experiment apparatus for adjusting a temperature using a thermoelement, a sensor for sensing a current temperature and a sensor for sensing an actual temperature are provided inside a chamber. The sensor for sensing the actual temperature corrects the sensed current temperature using a standard temperature calculation approximate expression of Newton or Lagrange by a numerical analysis. The intensity and polarity of direct voltage are supplied constantly to a plurality of fixed cooled thermoelements(5,5'). The intensity and polarity of direct voltage are supplied variably to a plurality of variable-type of thermoelements(6,6') A micom(9) controls the operations of the fixed cooled thermoelements and the variable-type of thermoelements with contact points by a plurality of relays(7,7') as to be suitable to a setting temperature. A control part includes the micom. A radiating plate(11) includes a pan(10) for heat absorption operated depending on the operations of the fixed cooled thermoelements and the variable-type of thermoelements.
