Guarded Hot Plate Thermal Conductivity Tester

The Guarded Hot Plate Thermal Conductivity Tester is designed to assess the thermal conductivity of various materials including plastics, glass, fibers, and foams. It operates under the principles of the guarded hot plate method, adhering to standards such as GB/T3392-82 for plastics, and other related standards for fiberglass and insulating materials. The device is integral for institutions involved in material performance assessment, quality assurance in manufacturing, and academic research.

The device offers a digital temperature measurement system with an accuracy of better than 0.2%. It supports test sample sizes of 200×200 mm or 300×300 mm with thickness options for accommodating different material forms. This thermal conductivity tester features dual heat flow and resistance measurement options, making it versatile for precise thermal analysis across a broad range of material properties.
