Introducing the C-THERM Thermal Conductivity Kit
An economical “do-it-yourself” solution, the TCkit is targeted primarily towards academic researchers. Employing the Transient Plane Source (TPS) method, the TCkit includes the tools & software needed to build and customize a thermal conductivity analyzer at a fraction of the price.
Paired with a standard Source Measure Unit (sold seperately), the TCkit is a great way to start testing thermal conductivity, now!

The TCkit from C-therm is simple-to-use and set up yet sophisticated in thermal analysis of a wide variety of materials such as low 'k' metals, rocks and almost all ceramics. This instrument is beautifully constructed that caters from enthusiastic students to learning and understanding the thermo-physical measurement of materials in the laboratory, to mature scientists wishing to characterize their novel materials. The Kapton coated double spiral Ni sensor is robust yet flexible to ensure efficient contact between the surfaces. The short measurement time enables multiple measurements within minutes and accurate values of thermal conductivity and thermal diffusivity can be obtained. Overall, great experience. Thank you C-therm!

C-Therm has been a pleasure to work with! The TCkit is a great tool in illustrating the fundamentals of heat transfer to my undergraduate students. I am very happy with this kit and would recommend it for others teaching the principles of thermal conductivity.

The TCKit offered us an affordable solution for learning more about the thermal conductivity of our sample materials. We were impressed with the service and support provided by C-Therm.
Principles of Operation
Transient Plane Source (TPS) Technique
The C-Therm TCkit, configured with the Transient Plane Source (TPS) technique, enables the characterization of thermal conductivity and diffusivity of materials. It employs a two-sided sensor, and the user iteratively develops the timing and power parameters. Intended for rough and heterogeneous materials that are not well-suited to a single-sided test method, this configuration allows researchers the maximum versatility in test parameters and experimental design. Variations of this technique, with a bridge circuit, are offered in accordance to ISO 22007.
HOW IT WORKS
(1) Power is applied to the sensor's spiral heating element, providing a small amount of heat. This results in a rise in temperature at the interface between the sensor and the sample, which induces a voltage change across the sensor element.
(2) The results from the initial scouting run are used to estimate test time, power level, and ideal sensor size. The experiment is run with the new parameters. This may need to be repeated until the correct parameters are identified. Guidance is provided in the ISO 22007-2.2.
(3) The test result is a plot of temperature vs time.
(4) The results are analyzed with an iterative solving procedure to generate thermal property data such as thermal diffusivity and thermal conductivity.
With the Transient Plane Source sensor included in the TCkit the thermal conductivity of solids can be characterized from 0.3 to 60 W/mK. Temperature stability from 10 to 80 °C means you can test under a variety of environments.
Versatile Thermal Conductivity Testing
C-Therm’s proprietary measurement and analysis software TECAS™ enables users to intuitively setup analysis, with post processing of data via an easy and visual platform. Running on Windows 10, direct export to CSV file allows for simple indexing of results.
