A research grade instrument for the direct determination of thermal conductivity of a wide range of low-to-medium thermal conductivity materials, including solid, liquid, paste, powder, thin film by using guarded heat flow method.
DTC 300 is a guarded heat flow meter measuring the thermal conductivity over a wide range of temperatures accordingly to the ASTM E1530 Standard.
It employs one calorimeter module, located in the bottom stack, 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.
Very versatile the DTC 300 covers an extremely wide conductivity range using three different stack modules easily interchangeable by the user. Tests can be run from -20°C up to 300°C. Typical sample size is 50mm (2”). Due to its flexibility and expanded analytical range the DTC 300 is ideally suited for research laboratories
