Thermal conductivity is an essential parameter for many industries, including automotive, aerospace, electronics and construction. Accurate thermal conductivity data is crucial for effective thermal management and ensuring the quality of the products.

Sourcing for a thermal conductivity measurement instrument can be deceptively simple. There are several methods that can be used to measure thermal conductivity – each with their own strengths, limitations, speed and sample assumptions, which would affect the accuracy and validity of the data obtained.

The choice of method to be employed is dependent on the sample conditions, such as:

• State of the sample – solid, powder, thin film, liquid, paste
• Sample dimensions, shape & conditions – bulk or directional (elongated, block, sheet, thin film) viscosity, phase changing
• Complexity of sample – homogeneous/heterogeneous (composites, fillers, crystalline, porous) or isotropic/anisotropic (axial, radial, through plane, in plane)
• Conductivity range (insulating or conductive)

Omega Scientific offers a comprehensive range of thermal conductivity measuring instruments based on different methods that are best suited for a variety of materials. We offer both portable and benchtop instruments; as well as steady-state or transient methods.
