Applications:

The F543 Dual-Plate Thermal Conductivity Tester is widely used for homogeneous plate materials such as rubber, glass, fiberboard, phenolic boards, extruded polystyrene (XPS) boards, foamed concrete, hollow glass, wooden boards, and various thermal insulation materials. It can also measure the thermal conductivity of granular materials, bulk materials, and soft materials.

The instrument is suitable for performance verification in new product development, quality control in production departments, third-party testing organizations, laboratory product performance validation, and material property testing by quality and technical supervision authorities.

Product Information:

The F543 Dual-Plate Thermal Conductivity Tester is equipped with an integrated constant-temperature water bath system, and all measurement and control functions are fully computer-controlled. It is mainly used for testing homogeneous plate materials such as plastics, rubber, glass, fiberboard, phenolic boards, extruded polystyrene (XPS) boards, foamed concrete, hollow glass, wooden boards, and various thermal insulation materials. It can also measure the thermal conductivity of granular materials, bulk materials, and soft materials. The instrument is widely applied in heat-resistant and thermal insulation material manufacturing enterprises, quality inspection institutions, universities, and research institutes.

Main structure

The instrument adopts a dual-plate thermal conductivity measurement method based on steady-state testing. Accurate results can only be obtained when the cold plate, hot plate, and guard plate reach thermal equilibrium under steady-state conditions. According to the one-dimensional steady-state heat transfer equation, the heat generated by the hot plate heater is transferred through the specimen to the cold plate, and then removed from the system by a circulating fluid or other working medium in the cold plate, forming a complete thermal cycle.

The instrument consists of two nearly identical specimens with a heating unit sandwiched between them. The heating unit is composed of a central circular or square heater and two metal face plates. The heat flow generated by the heating unit is conducted through the specimens on both sides and transferred to the respective cooling units (circular or square isothermal plate assemblies) on both ends.
