3kW Thermal Conductivity Testing Machine Measurement Heat Conduction Sensor
LRH-600 Thermal Conductivity Tester (Heat Shield Method) Measurement Heat Conduction Sensor
1. Description:
This instrument is based on the principle of unidirectional steady-state 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, to calculate the thermal conductivity. This instrument is designed for testing low thermal conductivity insulating materials and meets the high-precision testing requirements for the thermal conductivity of insulating materials in material testing and research departments.
2. Standard
GB/T3399-82 "Test Method for Thermal Conductivity of Plastics - Guarded Heat Plate Method", GB/T3139-2005 "Test Method for Thermal Conductivity of Fiber Reinforced Plastics (Thermal Conductivity Test Method for FRP)", GB/10294-2008 "Determination of Steady-State Thermal Resistance and Related Properties of Thermal Insulation Materials - Guarded Heat Flow Meter Method", etc. Mainly test materials such as plastics, vacuum glass, fibers, foams, powders, and gels. Widely used in material analysis and testing in colleges and universities, research institutions, quality inspection departments, and production plants.
