Thermal Conductivity Testing



ThermTest maintains a full-service thermophysical measurements laboratory servicing industrial, academic, environmental, government labs and commercial clients in North America and international markets.

ThermTest continues to upgrade laboratory instrumentation to meet the testing needs of our clients. We are especially proud to be able to offer the sale of multiple instruments and methods for measuring thermal conductivity, which is dependent on your sample type, testing temperature range, and sample dimensions.

Complete results report delivery in one to two weeks. We also offer one day service if needed.




Thermal Conductivity / Thermal Resistivity


Methods: TPS (ISO/DIS 22007-2.2), TLS (ASTM D5334), THW, TWA, HFM (ASTM C518), GHP (ASTM C177), PPMS, LFA (ASTM 1461)

Materials Solids, Liquids, Pastes & Powders
Thermal Conductivity Range 0.001 to 1800 W/mK
Thermal Resistivity Range 1000 to 0.001 C m/W
Temperature Range -272 C to 1600 C
Typical Accuracy, Precision 5%, 2%



Thermal Diffusivity


Methods: TPS (ISO/DIS 22007-2.2), THW, TWA, LFA (ASTM 1461)

Materials Solids, Liquids, Pastes & Powders
Thermal Diffusivity Range 0.1 to 100 cm2/s
Temperature Range -160 C to 1600 C
Typical Accuracy, Precision 5%, 2%



Specific Heat Capacity


Methods: TPS (ISO/DIS 22007-2.2), DSC (ASTM 1269), PPMS

Materials Solids, Liquids, Pastes & Powders
Heat Capacity Range Material Defined kJ/kg°C
Temperature Range -272 C to 1600 C
Typical Accuracy, Precision 5%, 2%



Thermal Effusivity


Methods: TPS (ISO/DIS 22007-2.2), THW, LFA (ASTM 1461), PPMS

Thermal effusivity is the square root of the product of thermal conductivity ( λ ), density (ρ) and heat capacity (cp), 
i.e. effusivity = ( λ ρ cp )1/2



Thermal Resistance


Methods: TPS (ISO/DIS 22007-2.2), TLS (ASTM D5334), THW, TWA, HFM (ASTM C518), GHP (ASTM C177), PPMS, LFA (ASTM 1461)

Materials Solids, Liquids, Pastes & Powders
Thermal Conductivity Range 0.001 to 1000 W/mK
Thermal Resistivity Range 1000 to 0.001 C m/W
Temperature Range -272 C to 1600 C
Typical Accuracy, Precision 5%, 2%
