A large laboratory scale medium temperature test apparatus capable of measuring the thermal conductivity in non-isotropic materials, such as composites is available at Engineering & Scientific Innovations Inc.
The ESI Thermal Conductivity Test Bed has the following characteristics:
-Test samples 3”x 3” in cross section and up to 0.5” in thickness.
-Hot side temperature adjustable between ambient and 550 °C.
-Apparatus thermal stability is +/- 2.3 % at 300 °C.
Thermal stability of the specimen surface is +/- 0.58 % or +/- 1.5 °C.
