DZDR-S Thermal Conductivity Meter for Materials

Product Introduction

The DZDR-S Thermal Conductivity Meter is a material thermal conductivity testing instrument based on the transient plane heat source (TPS) method. Developed through independent research and development, it combines stable measurement performance with intelligent data processing to evaluate the heat-transfer properties of a wide range of materials.

With a measurement range of 0.005–300 W/(m·K), the DZDR-S is suitable for testing metals, ceramics, polymers, composite materials, mineral-based materials, insulation products, and building materials. Its color LCD interface, automated data analysis, and report-generation functions help simplify laboratory testing and improve workflow efficiency.

The instrument supports measurements at temperatures from room temperature to 130°C and offers a configurable measurement duration of 5–160 seconds, making it suitable for material research, quality control, and thermal performance evaluation.

Working Principle

The DZDR-S thermal conductivity meter uses the Transient Plane Heat Source (TPS) method to characterize a material's thermal transport properties.

A plane heat-source probe is brought into contact with the test material. During measurement, the probe provides a controlled thermal stimulus and records the resulting temperature response over time. The instrument processes this response using the TPS measurement model to calculate thermal conductivity.

The measurement duration can be set within the specified range of 5–160 seconds. Actual testing conditions depend on the material properties, sample configuration, probe contact, and test procedure.
