Thermal Conductivity Tests

Materials that conduct heat readily with a small imposed temperature gradient have a higher thermal conductivity than materials that are more resistant more. What is thermal conductivity. The precise and accurate measurement of these properties is critical for any process or material which experiences a large or fast temperature gradient or for which the tolerance for temperature change is exacting.
