Introducing the DTC-300
Overview
The Discovery Thermal Conductivity (DTC-300) instrument is used for measuring the thermal conductiv-
ity of materials in the range 0.1 to 30 W/(m.K). These include some metals and ceramics, polymers, com-
posites, glass, rubber, and carbon products. The DTC-300 can also be used to test thin samples like paper
products and polymeric films. Non-solids of high viscosity can be tested using a special container to hold
the material.
Standard thermal resistance range is 0.002 to 0.02 m
2
K/W. Optional ranges are 0.0005 to 0.01 and 0.01 to
0.05 m
2
K/W.
The DTC-300 is configured to test a 50.8 mm diameter sample. The instrument operates from -20 to
300°C–a suitable chiller/circulator is required to test from -20 to 20°C. Chiller setpoint temperatures must
be a minimum of 15°C below the desired sample temperature.
Input power options include 100–120 VAC or 200–240 VAC. Please check your instrument and make cer-
tain that you have received the option you ordered.
The DTC-300 system (shown below) is comprised of the test stack and electronic enclosure. The instru-
ment is PC-controlled and the operational software is also used to generate tabular and graphical data.
