The DTC-300 measures thermal conductivity of a variety of materials, including polymers, ceramics, composites, glasses, rubbers, some metals, and other materials of low to medium thermal conductivity.
Only a relatively small test specimen is required. Non-solids, such as pastes or liquids, can be tested using special containers. Thin films can also be tested accurately using a multi-layer technique. The tests are in accordance with the ASTM E1530 Standard.

DTC-300 Features
Each DTC-300 is factory calibrated using specimens of known thermal resistance, spanning the particular range. The contact resistance is kept small by applying a reproducible, pneumatic load to the test stack, and a thermally conductive interface compound. A guard furnace surrounds the test stack to reduce the effect of heat transfer across the edges of the
specimen.

Flexible Temperature/Specimen Options
Using tap water, the heat sink provides operation down to a specimen temperature of about 50°C. To fully utilize the range of the instrument an optional chiller circulator can be used to provide a heat sink temperature down to -10°C. The instrument is provided with one of three operating range modules. Each module covers a different thermal resistance region. The various modules are field exchangeable.

System Software
Each DTC-300 system includes Windows™ operating and data analysis software. The user simply specifies
certain test parameters, including specimen size and desired test temperatures, and the equipment runsunattended until test completion, when thermal conductivity results are printed and plotted.
