Abstract: This research article proposes the use of a thermal constants analyzer to measure thermal properties of relatively thin samples. Five different metallic samples containing copper, aluminum and brass were used to test the accuracy of the new and improved method. Previously, this method has been used to test the thermal properties of thin metallic sheets, however with the new and improved method, it is possible to measure samples with thicknesses as small as 10 cm3. Researchers also determined that the specific heat of a given material may also be measured, in transient readings, by lengthening the test time. Comparing the new and improved method to the old method, an accuracy of below 1% is seen, however the accuracy is usually about 0.5%.
