DRH-III double plate thermal conductivity measuring instrument protective hot plate meter
I. Product description
DRH double plate thermal conductivity tester is based on the principle of unidirectional stable thermal conductivity. When the upper and lower sides of the sample are at different stable temperatures, the heat flow through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces of the sample are measured to calculate the thermal conductivity. It meets the requirement of high precision test for thermal conductivity of materials. Automatic data acquisition, data processing, printing reports, data storage. The advantages of short measurement time, accurate data, good repeatability and high degree of automation.
