Your perfect accessory for testing liquids. The Small-Volume Liquids Test Cell was originally developed with the US Navy Surface Warfare Division specifically for testing energetic emulsions and powders. The effectiveness of the accessory in reducing convection effect on testing samples make it ideal for characterizing the thermal conductivity of liquid samples regardless of the viscosity. The Liquids Test Cell is commonly applied in testing nano and heat transfer fluids, as well as emulsions. (Note: does not include sensor or sensor base – sold separately.)

Get a QuoteThe Compression Test Accessory (CTA) is engineered and designed to enable users to precisely control the level of compression or compaction of a sample in characterizing the material’s thermal conductivity. The CTA is ideal for applications in the fields of advanced textiles, fabrics and thermal interface materials (TIMs) where representative thermal conductivity data requires precise control over the sample’s compaction. The CTA is compatible with solids, pastes, greases and powder sample formats.

Get a QuoteC-Therm's TCi system offers fast and accurate measurement of the thermal conductivity of materials. The MTPS high precision method is the simplest and most versatile transient method.
Simple and Precise. The MTPS method employs a single-sided sensor to directly measure thermal conductivity and effusivity of materials. The MTPS method has the highest precision, highest sensitivity, shortest test time, and is the easiest to use among all three techniques.
Principles of OperationTCi’s primary sensor employs the Modified Transient Plane Source (MTPS) technique in characterizing the thermal conductivity and effusivity of materials. It employs a single-sided, interfacial heat reflectance sensor that applies a momentary constant heat source to the sample. Typically, the measurement pulse is between 1 to 3 seconds. Thermal conductivity and effusivity are measured directly, providing a detailed overview of the heat transfer properties of the sample material.
C-Therm has a new instrument called Trident!
Equipped with the Modified Transient Plane Source (MTPS), Transient Plane Source (TPS), and Transient Line Source (TLS), Trident allows the sensor to conform to your sample, and not the other way around.
Trident can be configured with these sensors to best match your needs for rapid and accurate thermal testing for solids, liquids, powders, and pastes. To learn more about Trident and the applications for each sensor, click here!
