LRH-GW Thermal Conductivity Tester (High-Temperature Heat Shield Method) Thermal Resistance Instrument
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, as well as the temperature difference and thickness between the two surfaces of the sample, and calculates the thermal conductivity. This instrument is designed for the testing of low thermal conductivity insulating materials and meets the high-precision testing requirements for the thermal conductivity of insulating materials by the material testing research departments.
2.Standard
GB/T 3139-2005 (Test Method for Thermal Conductivity of Fiber-Reinforced Plastics) (Test Method for Thermal Conductivity of Fiberglass)
GB/10294-2008 (Determination of Steady-State Thermal Resistance and Related Properties of Insulation Materials - Protective Heat Plate Method) are among them. The main tests are conducted on materials such as plastics, vacuum glass, fibers, and foams. They are widely used in material analysis and testing in universities, research institutions, quality inspection departments, and production plants.
3.Feature:
1. Automatic thickness measurement: Utilizing high-precision displacement sensors for measurement and connecting to a computer for automatic thickness measurement, thereby reducing human error.
2. Automatic Pressurization System: The system automatically applies pressure. It enables the measurement of thermal conductivity under various pressure conditions. This method is more scientific, data-driven, and has higher repeatability compared to manual pressure application.
3. Various measurement types: In addition to measuring hard plates, by selecting various accessories from the company, it is possible to measure a wide range of special materials. For example: granular materials, loose materials, soil, etc.
