LRPL-III ASTM C 518 Thermal Conductivity Analyser For Insulation Materials
LRPL-III ASTM C 518 Heat Conductivity Analyzer for Insulation Materials
1.Description:
This instrument uses the internationally popular heat flow meter method to measure thermal conductivity and thermal resistance, and is equipped with a computer to achieve fully automatic testing and generate test reports. It is suitable for testing the thermal conductivity of low thermal conductivity materials such as insulation materials and refractory materials. With the addition of a sample frame, it can also be used to test powder materials. It is widely used in colleges and universities, research institutes, quality inspection agencies, and factories and mines.
2.Standard
GB/T 10295-2008 (Determination of Steady-State Thermal Resistance and Related Properties of Insulation Materials - Thermal Flow Meter Method) and ASTM C518-04 - Test methods for determining steady-state heat flux and heat transfer properties using the thermal flow meter method.
