C-Therm - Model TCkit -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!

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.
- 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.
- 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.
- The test result is a plot of temperature vs time.
- 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 0.03 to 60 W/mK. Temperature stability from 10 to 80 °C means you can test under a variety of environments.
