1.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, the temperature difference between the two surfaces of the sample, and the thickness, and calculates the thermal conductivity. It meets the high-precision testing requirements of material testing research departments for the thermal conductivity of materials.
2.Standard
GB/T3399 "Test Method for Thermal Conductivity of Plastics - Thermal Shield Plate Method", GB/T3139-2005 (Test Method for Thermal Conductivity of Fiber Reinforced Plastics) (Test Method for Thermal Conductivity of Fiberglass Reinforced Plastics),
GB/10294-2008 "Determination of Steady-State Thermal Resistance and Related Properties of Insulation Materials - Protective Heat Plate Method", etc. The main tests include plastics, glass, fibers, foams, insulation materials, etc. It is widely used in large and medium-sized colleges and universities, research institutions, quality inspection departments and production plants for material analysis and testing.
