High Precision Heat Flow Thermal Conductivity Tester
Published: 11/11/2016
The High Precision Heat Flow Thermal Conductivity Tester DRH300 utilizes the heat flow meter method to measure the thermal conductivity and resistance of various insulating materials. It is used in industries requiring precise thermal conductivity measurement, such as materials science and construction.
Product Description
The DRH300 High Precision Heat Flow Thermal Conductivity Tester is designed to measure the thermal conductivity and resistance of insulating and other materials like clay, sand, ceramics, and plastics. It complies with the standards ASTMC518, ISO8301, and GB/T10295. The tester functions through dual heat flow sensors and integrates with a computer for automatic detection, data collection, processing, and reporting.
The instrument is particularly appreciated for its precise control of plate temperature and the dual heat flow sensor configuration, which ensures quick stabilization and fast response to sample characteristics. It can conduct rapid and accurate measurements, making it ideal for quality control and process monitoring, with some tests requiring less than five minutes.
