Thermal Conductivity Tester

The DRX-II-RL Thermal Conductivity Tester utilizes the heat flow method to measure different materials' thermal conductivity, thermal diffusivity, and thermal resistance. This device is designed to automatically perform all testing functions with motor-controlled plate movement, where samples are clamped between two heat flow sensors. The instrument tests samples within a diameter range of 10 to 50 mm and a thickness range of 0.1 to 40 mm. It can maintain a fixed or adjustable temperature gradient with the thermal conductivity and thermal resistance determined using an embedded controller or an external computer. The product complies with relevant international standards such as MIL-I-49456A, ASTM E1530, and ISO 8301.

The tester is designed to handle various materials including polymers, ceramics, insulation materials, composites, non-metals, glass, and rubber. It requires relatively small sample sizes, and films can be measured using multilayer technology for accurate results. With a full suite of automatic testing software, this tester can analyze and print reports quickly and accurately, making it ideal for research and quality control applications across industries that work with a wide range of thermal properties.
