Thermal Conductivity

AMI uses a TA Instruments DTC-300.

Thermal conductivity measures the ability of a material to transfer heat. The DTC-300 is a guarded heat flow meter that can measure the thermal conductivity over a wide range of temperatures. It employs one calorimeter module for the measurement of thermal conductivity, and a side guard furnace to prevent edge heat loss. The contact resistance is minimized by applying a pneumatic load to the test stack, and by using a thermally conductive interface compound. It can measure the thermal conductivity of a variety of materials, including polymers, ceramics, composites, glasses, rubbers, some metals, and other materials of low to medium thermal conductivity. Non-solids, such as pastes or liquids, can be tested using special containers.

For a sample, we need: 50 mm (diameter)× 25mm (thickness) max or liquid
