Transient Hot Wire (THW)

THW is a proven method for measuring thermal conductivity in fluids, providing fast, reliable data for formulation, qualification, and temperature-dependent performance analysis.

Fluid Thermal Conductivity Benchmark

Fast, reliable conductivity data for fluids

THW determines thermal conductivity by monitoring the transient temperature response of a heated wire immersed in the sample. It is a well-established approach for liquids and fluid-like systems where accurate conductivity data is needed for product development and thermal management design.

Typical use cases include lubricants, specialty fluids, and application media where temperature dependence is important. Method quality relies on stable thermal conditions, clean sample handling, and controlled measurement timing. When implemented with good laboratory discipline, THW delivers dependable conductivity values that support fluid comparison, specification work, and performance verification across operating ranges.
