Insulation Material Thermal Conductivity Tester
Published: 3/2/2017
The DRH300 measures thermal conductivity and thermal resistance of insulation and related materials using the heat flow meter method. It complies with ASTM C518, ISO 8301, and GB/T 10295 for quality control, R&D, and process monitoring applications.
Product Description
The DRH300 is a heat flow meter method thermal conductivity tester designed for board-like insulation and materials such as clays, sands, ceramics, and plastics. It employs a symmetric dual heat-flow sensor configuration with a hot plate and a cold plate to achieve rapid stabilization and high repeatability.
The system offers fully automated operation from temperature control to data acquisition and analysis. Users can generate test reports, store data, and optionally operate via an embedded touchscreen interface; PC-based control and analysis software are included.
