DRL-III ,Thermal conductivity tester(heat flow method)

Overview

This instrument is mainly used for testing thermal insulation、 the contact thermal insulation of solid interface and thermal conductivity of thin materials, such as aluminum panels, solid electrical insulation materials, thermal conductivity of resin, ceramic and so on。Detection of solid sheet of material，Can be detected powder materials and paste materials with a sample frame . Instrument Reference Standard: MIL-I-49456A、GB 5598-85 Thermal conductivity of beryllium oxide ceramic Determination、ASTM D 5470 – 12 Standard Test Method for Thermal Transmission Properties of Thermally Conductive Electrical Insulation Materials。

Instrument Features: Automatic pressure, automatic thickness measurement, automatic control experiments. use 6-point temperature gradient detection, improve test accuracy. Can detect the thermal insulation curve under different pressure, Use an optimization mathematical model to test the thermal insulation、 contact thermal insulation of solid interface and thermal conductivity
