The Thermal Constants Analyzer is a non-destructive precision analysis of thermal transport properties including thermal conductivity, thermal diffusivity, and specific heat capacity. The analyzer operates on a wide variety of sensors with radius from 0.5 mm to 30 mm. The test machine operates by pulsing energy into a circular disk sensor and reading a difference in resistivity values over time. These values change as heat is introduced to the material under test. There are two main differentiations between material types. Those that are Isotropic: meaning (the properties are the same in all directions i.e. metals) or Anisotropic: meaning (properties are not the same in all directions i.e. carbon fiber composites). The software for this machine allows RFAL to determine properties for both Isotropic and Anisotropic materials. Advantages: Contact resistance between sensor and sample does not influence measurement results Porous and transparent samples are easy to test without modification Surface roughness or color does not influence measurement results Minimum or no sample preparation time Double-sided testing for maximum accuracy Three thermal transport properties testing in a single transient No calibration or reference sample required .
