LRH-300 Multifunctional Fast Thermal Conductivity Tester Thermal
Single Plate Protection Method
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.
