Multifunctional Rapid Thermal Conductivity Tester (TPS & Hot Disk Method)

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.

Parameters

Features

Rapid measurement: 1–120 seconds testing time saves significant laboratory time.

No contact resistance influence: TPS method avoids errors from contact resistance in steady-state methods.

Minimal sample preparation: Solid samples require only a relatively flat surface; powders, pastes, and liquids are easily accommodated with specialized test holders.

Versatile testing: Supports thin materials, high thermal conductivity (100–500 W/m·K), low conductivity insulation (0.010–0.050 W/m·K), and anisotropic materials.

Full automation: Software-controlled testing, data analysis, and report generation.

Compact design: Integrated unit saves space and allows easy installation.

Accessories

Main instrument

Analysis software (Chinese & English versions)

Two quartz reference samples

Accessory kit: paste, powder, and liquid test holders; sample fixture for solid materials

Test Procedures

Prepare the sample according to its state: solid, powder, paste, liquid, or thin film. Solid samples require a relatively flat surface.

Place the Hot Disk probe on or within the sample. Use the appropriate fixture for powders, pastes, or liquids.

Configure test parameters via the software, including probe diameter, temperature, and material type.

Start the test; the software records temperature changes over time.

Software calculates thermal conductivity, thermal diffusivity, specific heat, heat storage coefficient, and thermal resistance.

Review data and generate the report.

Maintenance Information

Keep the Hot Disk probe clean and free from residues.

Calibrate periodically using quartz reference samples.

Check the integrity of sample holders and fixtures before each test.

Maintain a stable laboratory environment to ensure measurement accuracy.

Store the instrument in a dry environment to protect electronic and thermal components.

FAQ

1. What types of materials can tester test?

The tester can test metals, alloys, graphite, thermal pastes, silicone, rubber, ceramics, polymers, paper, fabrics, foams, concrete, composite panels, honeycomb boards, powders, liquids, pastes, coatings, thin films, insulation materials, and anisotropic materials. The system adapts to various states using dedicated test holders.

2. How fast is the measurement process?

Measurements typically take 1–120 seconds, depending on sample type and probe configuration. This speed is achieved using the TPS method, which measures transient heat propagation, eliminating the lengthy stabilization times required in steady-state methods. The software automates the entire process from data acquisition to report generation.

3. Does tester require sample preparation?

For solid materials, only a relatively flat surface is needed. Powders, pastes, and liquids are placed into specialized sample holders. Thin films, high-conductivity materials, and insulation require specific mathematical models integrated into the software to ensure accurate results without extensive sample preparation.

4. Can tester operate under extreme temperatures or vacuum conditions?

Yes. The instrument can be optionally equipped with high- and low-temperature test chambers (-40–250 °C) and vacuum test modules. These options must be specified at the time of purchase and are subject to additional agreement and fees.
