C-Therm, the world leader in thermal conductivity testing, is proud to partner with SciMed to expand access to advanced thermal conductivity instrumentation across the UK and Ireland. This partnership helps engineers, researchers, and manufacturers access industry-leading thermal property testing equipment, backed by local sales, application support, and service.
SciMed is a UK-based scientific instrumentation company with a long history of supporting technical teams across a wide range of industries. Now representing C-Therm throughout the region, SciMed provides local support for customers working across thermal analysis and thermal property measurement applications.
In this webinar, we introduce C-Therm’s Trident instrument, a modular transient thermal conductivity testing platform designed to give users access to multiple methods within one system. Trident can be equipped with up to four transient techniques: Modified Transient Plane Source (MTPS), Flex Transient Plane Source (TPS), Transient Line Source (TLS), and Transient Hot Wire (THW). These methods allow users to measure the thermal conductivity of solids, liquids, powders, pastes, textiles, soils, and anisotropic materials.
We also discuss why transient methods are increasingly preferred for thermal conductivity measurement due to their fast test times, ease of use, broad sample flexibility, and ability to test under representative conditions such as temperature, pressure, humidity, and controlled atmosphere.
Application areas covered include:
Aerospace and Defence: Thermal interface materials are critical for electronics and electronic systems. These materials are often filled with thermally conductive additives, and one challenge is assessing filler settling and dispersion. We highlight thermal mapping using C-Therm’s MTPS method, which enables localized thermal conductivity measurements through its patented guard ring design that promotes unidirectional heat flow.
We also discuss high thermal conductivity graphite and graphene-based heat spreader materials, including pyrolytic graphite. For these materials, the TPS slab utility is used to accommodate thin, high-conductivity sample formats. Battery testing is another key area, especially for battery pouches and other layered materials with anisotropic thermal behavior. Using the anisotropic utility with the single-sided TPS method, users can characterize thermal conductivity in both axial and radial directions.
Heat Transfer Fluids: Thermal conductivity is an important property for liquid cooling fluids used in data centers and other high heat flux applications. THW is the recommended method because it is fast and minimizes the effects of convection. MTPS can also be used when smaller sample volume is preferred, while TLS may be suitable for highly viscous liquids.
Textiles: Thermal effusivity relates directly to the warm or cool feel of a material. C-Therm’s MTPS method conforms to ASTM D7984 for measuring the thermal effusivity of fabrics and offers key advantages including a patented guard ring, TX calibrations, direct effusivity measurement, and compression control. We also discuss testing wetted textiles.
Geothermal: Thermal conductivity is important for geothermal materials including rocks, soils, and thermally conductive grouts. We also highlight soil testing using TLS.
Hydrogen Storage: Metal hydrides used for hydrogen storage require testing under representative conditions including hydrogen atmosphere, high pressure, and elevated temperature. TLS can be used for powdered samples, while TPS can be used for pelletized samples.
This webinar provides a practical introduction to modern thermal conductivity testing and shows how C-Therm and SciMed help teams across the UK and Ireland solve heat transfer challenges across advanced materials, energy systems, aerospace components, fluids, textiles, and more.
