The DTC-25 is an entry-level, single temperature test instrument used for quick determination of thermal conductivity of solid materials using the guarded heat flow method. Because of its simple operation, small specimen size, and short cycle time,the DTC-25 is ideally suited for research, quality control and screening of materials. 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, with the help of an optional software package.

Simple, Efficient, Economical
The DTC-25 is completely self-contained and requires no additional instrumentation for the measurement.An optional chiller providing coolant at a fixed temperature is recommended for optimal performance. TheDTC-25 is a simple, fast, accurate, and reasonably-priced laboratory instrument.

System Software
The DTC-25 test method is in accordance with specification ASTM E1530 for measuring thermal conductivity.
The unit is supplied with a utility software program for convenient data analysis. The user simply enters data from the DTC-25 digital display via the computer keyboard and the thermal conductivity is automatically computed. If the measured thermal resistance value falls outside the range of the instrument, the program suggests testing a different specimen thickness for obtaining more accurate test results.
