Abstract
Apparatuses and methods for using the guarded heat flow meter technique are provided. The apparatuses use the guarded heat flow meter method to measure the thermal conductivity of solid materials in the temperature range of about ambient to 300° C. The material being tested is compressed between two plates with a controlled temperature difference. The thermal conductivity of the material is calculated by measuring the heat flux through a reference sample in series with the material under test. The apparatuses and methods comprise mechanical mechanisms for stack and guard movements and methods of stack compression and measurement for the testing.
