LRH-300 Thermal Performance Analyzer for Heat Insulation Materials
Description:
This instrument is based on the principle of unidirectional stable heat conduction. When the upper and lower surfaces of the sample are at different stable temperatures, it measures the heat flow through the effective heat transfer area of the sample, as well as the temperature difference and thickness between the two surfaces of the sample, and calculates the thermal conductivity. It meets the high-precision testing requirements of material testing research departments for the thermal conductivity of materials. This instrument mainly tests plate-like materials such as plastics, fibers, foams, extruded boards, concrete, aerogels, insulation materials, heat insulation materials, and refractory materials. It is widely used in enterprises producing heat-resistant and insulation materials, quality inspection departments, universities, and research institutes and other scientific research units.
