Classification: CPC F  G  H | IPC F  G  H

Claim 0:
1. A temperature control device for use in measuring thermal properties of materials, comprising:
a test cell for receiving a sample to be measured;
a heating subsystem configured to supply thermal energy to the test cell;
a chill cell surrounding at least a portion of the test cell and the heating subsystem;
a thermal break separating the chill cell from the test cell and the heating subsystem, wherein the chill cell is configured to remove thermal energy from the test cell through the thermal break when cooled, and the thermal break is configured to allow a controlled amount of heat transfer between the chill cell and the test cell;
a cooling subsystem configured to cool the chill cell; and
a controller configured to control the heating subsystem to supply thermal energy to the test cell while thermal energy is simultaneously removed from the test cell using the cooling subsystem, to control a temperature of a test volume inside the test cell to a set temperature.
