To measure the thermal conductivity with the RDC-143 apparatus, high precision of the parallelism of the sample’s surfaces is required to obtain correct measurements.
The RDC-149 apparatus provides the required precision. A core sample with a diameter of 30 or 50 mm can be cut to a height of 20 mm by two planar and parallel discs.
Alternatively, for a typical anode evaluation, this sample preparation can be done in one step by using the RDC-140 equipment.
