Chapter 1:
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 m2K/W. Optional ranges are 0.0005 to 0.01 and 0.01 to
0.05 m2K/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.

DTC-300 Getting Started Guide Page 12
DTC-300 System Components
A DTC-300 system has two major components: DTC-300 electronic enclosure and the test stack.
Electronic Enclosure
The DTC-300 electronic enclosure contains the system electronics used to read and display the output of
the temperature sensors.
DTC-300 Front Panel
The heater control for each of the heaters is sensed and automatically adjusted by the software, and can
also be adjusted manually using the PID temperature controllers located on the front of the electronic
enclosure. The various parameter settings are preset at the factory and should not be adjusted or manipu-
lated without first consulting TA. These parameters are re-initialized at the beginning of each test to ensure
proper starting conditions. An independent over-temperature monitor is employed as a safety for the
device. The fault indicator on the front panel lights when an over-temperature condition is detected. Pres-
sure applied to the sample can be adjusted using the air pressure regulator and monitored on the built-in
pressure gauge. The movement of the test stack is controlled with the UP/DOWN, FREE/MOVE, and
SPEED switches.
Refer to Figure 2 below for the locations of knobs, switches, and indicators on the DTC-300 front panel
and refer to Table 1 for a description of their functions.

Test Stack
The sample to be tested is held under a reproducible compressive load between two polished metal sur-
faces (the “test stack”), each controlled at a different temperature. The lower contact surface is part of a
calibrated heat flux transducer. As heat flows from the upper surface through the sample to the lower sur-
face, a uniaxial temperature gradient is established in the stack. By measuring the temperature difference
across the sample along with the output from the heat flux transducer, thermal conductivity of the sample
can be determined when the sample thickness is known.
