  • Direct thermal conductivity measurement technique
    Patent number: 6676287
    Abstract: The thermal conductivity of a sample of interest is measured by applying backing material to a sensor to substantially surround the sensor with the backing material and the tested material. The instrument response of the sensor corresponds to the thermal conductivity of the combination of the tested sample and the backing material. The instrument is calibrated to cancel effects of the backing material out of the instrument response.
