    Testing Thermal Conductivity of Powders

    The testing of powders is a difficult measurement, due to the contact resistance created by loose solids.

    “Thermtest and Craig Dixon thank you very much for your time and support. We are looking forward to our next tests and service.”

    Transient Plane Source

    The equipment has the unique ability to be able to test thermal conductivity on powders of small and large particles. This is due to the method having a variety of sensor diameters and variable test times. The sensor sizes and test times may be increased as the particle size increases to create better contact between the sensor and sample.
