thermal conductivity test machine

Multifunctional Rapid Thermal Conductivity Tester (Integrated Unit) is a high-precision instrument based on the Transient Plane Source (TPS) method, utilizing a Hot Disk probe. It measures thermal conductivity, thermal diffusivity, specific heat, heat storage coefficient, and thermal resistance of solid, powder, liquid, paste, coating, thin-film, insulation, and anisotropic materials.

The instrument provides rapid and accurate testing, avoiding contact resistance errors inherent in steady-state methods. Minimal sample preparation is required; solid materials only need a relatively flat surface. The tester supports various test protocols and mathematical models for different material types, offering broad applicability, fast testing, and reliable results.

Reference standards: ISO 22007-2:2015. GB/T 32064-2015.

Thermal conductivity testers are generally classified into two main categories: Steady-State and Transient (Non-Steady-State) methods. Steady-State testers offer high precision for controlled environments, while Transient meters provide quick, versatile assessments across various materials.

The most common types of testers include:

1、Thermal Conductivity Tester (Hot Disk Method)

2、Thermal Conductivity Tester – Heat Flow Meter

3、Guarded Hot Plate Heat Flow Meter (GHP/TLR)

4、Thermal Conductivity Tester(Transient Fast Hot-Wire Method)

5、Thermal Conductivity Tester(Light/Laser Flash Method)

6、Thermal Conductivity Tester(Transient Plane Heat Source Method)

7、Fully Automatic Dual-Plate Thermal Conductivity Tester (Guarded Hot Plate Method)

8、High-Temperature Thermal Conductivity Tester
