Thermal Conductivity Measuring Instruments

THERMAL CONDUCTIVITY & DIFFUSIVITY

Thermal diffusivity is a measure of the ability of a substance to transmit a difference in temperature, expressed as the thermal conductivity divided by the product of specific heat capacity and density. Thermal conductivity is a measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow: measured in watts per metre per kelvin. Symbol λ, κ sometimes shortened to conductivity.

Laser flash apparatus (LFA) is one of the most popular laboratory equipment to measure thermal diffusivity, and the thermal conductivity can be calculated with known density and specific heat capacity.

TIM-Tester is an instrument used for the analysis and determination of thermal impedance properties of thermal interface materials such as thermal fluids, thermal pastes (greases), phase change materials (PCM), solders or resilient thermal conductors.

Heat flow meter is useful for determination of thermal conductivity for low thermal conductivity materials such as insulation materials.

The Transient Hot Bridge method (THB) is a direct measuring method which is fast, easy, and accurate for solids, liquids and pastes as well as isolating materials and metals.
