    Abstract: A device is provided. The device includes a body, a heat absorber, a test piece and a contact thermometer. The heat absorber is attached to the body. The test piece is attached to the body and spaced apart from the heat absorber. The test piece has an overlap region that is overlapped by the heat absorber such that the heat absorber absorbs heat radiated toward the device and a non-overlap region which does not overlap with the heat absorber and which is exposed to the heat radiated toward the device. The contact thermometer is coupled to the overlap region. The test piece has a thermal transmissivity approximately equal to that of a substrate, and the device positions the overlap region of the test piece adjacent to the substrate being radiated by the heat.
