Product Description

DRH-III automatic double flat thermal conductivity detector is based on the principle of unidirectional stable thermal conductivity, when the specimen, the lower sides in different stable temperature, measured by the sample effective heat transfer area of the heat flow and sample temperature difference between the two surfaces and thickness, calculated thermal conductivity. Meet the high-precision test requirements of the the material detection research department of the thermal conductivity of the material. My company independent research and development of electronic circuits, computer software for the whole process of automatic monitoring and control. This machine has a computer automatic thickness measurement, automatic compression, measuring the thermal conductivity pressure. Automatic data acquisition, data processing, print reports, and data storage. Measuring short time, accurate data, good repeatability, high degree of automation. 

Uses: 
The thermal conductivity detector test plastics, rubber, glass, fiber, benzene board, extruded sheet, foam concrete, hollow glass, wood, insulation materials homogeneous plate material, at the same time can be measured pellets, bulk material , soft materials such as the thermal conductivity of the various substances
