Thermal Conductivity Tester
The Intelligent Flat Plate Thermal Conductivity Tester is a state-of-the-art laboratory instrument designed to measure the thermal conductivity of a wide range of materials, including plastics, rubber, glass, fiberboard, polystyrene boards, extruded boards, foamed concrete, hollow glass, wood panels, and various insulation materials. It also supports measurements of granular materials, powders, and soft materials. By integrating a water bath constant temperature system with full computer control, the instrument ensures fast, accurate, and highly automated thermal conductivity measurements.
The system utilizes a Visual Basic 6.0 interface for intuitive operation. Test data is saved in Excel format for easy processing, and real-time curves can be printed or stored, allowing full documentation of each experiment. The automated system enables precise control, data acquisition, calculation, display, and printing of thermal conductivity results with minimal noise and high efficiency.
