Features

Direct measurement of heat transfer behavior, significantly reducing testing time

Minimal influence from contact thermal resistance compared with steady-state methods

No special sample preparation required for solid materials with relatively flat surfaces

Wide measurement range suitable for both high and low thermal conductivity materials

Flexible testing schemes and mathematical models for different material types

Effective suppression of natural convection effects during measurement

Fast testing speed with stable and repeatable results

Fully automatic testing software for data analysis and report generation

Accessories

Hot Disk sensor (standard Φ15 mm probe)

Optional probes: Φ30 mm, Φ15 mm, Φ7.5 mm, Φ4.0 mm (–40 to 250 °C)

Solid sample clamping fixture

Powder, paste, and liquid sample testing cell

Dedicated thin-sample testing configuration

Optional temperature control chamber (–40 to 250 °C)

Optional vacuum testing configuration

Test Procedures

Select an appropriate probe and testing mode according to material type and thermal range.

Place the Hot Disk sensor between two solid samples or insert it into the dedicated sample holder for powders, liquids, or pastes.

Ensure proper contact between the probe and sample surface without special surface treatment.

Set test parameters such as power, time, and temperature conditions in the software.

Start the test; the system automatically records transient temperature response.

The software calculates thermal conductivity and related parameters using the corresponding mathematical model.

Review results and export test reports upon completion.

Maintenance Information

Keep the Hot Disk probe clean and free from mechanical damage during handling and storage

Avoid excessive bending or pulling of probe leads

Periodically verify system performance using reference materials

Ensure stable power supply and appropriate environmental conditions during operation

Store probes and accessories in protective containers when not in use
