Multi-Function Thermal Conductivity Measurement Platform is an absolute-method measurement system designed for accurate determination of thermal conductivity, thermal diffusivity, specific heat capacity, and thermal effusivity of solids, liquids, pastes, and powders. By integrating multiple transient techniques on a single platform, the system enables direct calculation of thermal properties from raw data without calibration materials, supporting reliable and repeatable measurements across a wide range of material types.

Application

The Multi-Function Thermal Conductivity Measurement Platform is suitable for thermal property evaluation in research, quality control, and material development, including:

Polymers, composites, and building materials

Liquids and phase-change materials

Pastes, powders, and bulk solids

Soil and polymeric materials

Typical test samples include solid blocks and plates, liquid samples, powders, pastes, and soil specimens, depending on the selected sensor and test method.

Standards

The platform supports internationally recognized absolute measurement standards, including:

(1) ISO 22007-2: Plastics — Determination of thermal conductivity and thermal diffusivity — Transient plane heat source method

(2) ISO 22007-7: Plastics — Determination of thermal conductivity and thermal diffusivity using transient plane heat source

(3) GB/T 32064: Transient plane heat source method for thermal conductivity and thermal diffusivity of building materials

(4) ASTM E3088: Determination of thermal conductivity and thermal diffusivity using the transient plane source method

(5) ASTM D7896: Transient hot-wire method for thermal conductivity, thermal diffusivity, and volumetric heat capacity of liquids

(6) ASTM D5334: Transient line-source probe method

(7) ASTM D5930: Determination of thermal conductivity of plastics by transient line-source technique
