Flat plate heat flow meter thermal conductivity tester

DRH-30SFlat plate heat flow meter thermal conductivity tester

This thermal conductivity meter uses the heat flow method to measure the thermal conductivity, thermal diffusivity, and thermal melting of different types of materials.

This instrument is based onstandardASTMD5470Standard Test Method for Thermal Transmission of Thermal Conductive Electrical Insulation Materials.

Reference standard:ASTM C518-04Test method for determining steady-state heat flux and heat transfer characteristics using a heat flux meter;GB10295-2008 Measurement of steady-state thermal resistance and related characteristics of insulation materials (heat flux meter method);GB/T25261-2018Appendix for Reflective Thermal Insulation Coatings for BuildingsAThe requirements for determining the thermal conductivity coefficient,Waiting for relevant international standards.

The flat plate heat flux meter and thermal conductivity tester are capable of measuringPlastic, rubber, glass, fiber, polystyrene board, extruded board, foam concrete, hollow glassCeramics,岩石、岩土、Fully automatic detection of thermal conductivity and resistance of refractory materials, polymer composite materials, nylon, resin, insulation materials, thermal insulation materials, etc., with automatic pressurization and thickness measurement functions, capable of testing under different pressures and reducing manual measurement errorsThin films can be accurately measured using multi-layer technology.

The principle of measuring according to the standard GB/T 25261-2018 "Reflective Thermal Insulation Coatings for Buildings" is to position the sample between a hot plate and a cold plate to measure the heat flow. It can operate independently or under PC control, providing fast and accurate measurement results.applied toMaterial performance testing institution，Scientific research institutions (institutes)The quality inspection department of the factory,Higher InstituteSchool Teaching and Research.
