Xiangtanxiangke DRH-600 thermal conductivity Tester (Heat protection plate method)
This instrument Based on the principle of unidirectional stable heat conduction, when the upper and lower surfaces of the sample are at different stable temperatures, measure the heat flow through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces of the sample to calculate the thermal conductivity. The instrument is designed for testing low thermal conductivity insulation materials, and meets the requirements of the material testing and research department for high-precision testing of thermal conductivity of insulation materials. Instrument reference standards: GB/T3399-82 Test Method for Thermal Conductivity of Plastics, Hot Plate Method, GB/T3139-2005 (Test Method for Thermal Conductivity of Fiber Reinforced Plastics)（ FRP Test Method for Thermal Conductivity), GB/10294-2008 (Determination and Protection of Steady State Thermal Resistance and Related Properties of Thermal Insulation Materials hot plate France), etc. Mainly test plastic Vacuum glass , fiber, foam, powder, gel and other materials. It is widely used in the material analysis and detection of universities, scientific research institutions, quality inspection departments and manufacturers.
