DRL-VIIIThermal Conductivity Meter

One,Overview

This instrument primarily tests the thermal resistance of thin thermal conductors, thermal conductive silicone sheets, thermal conductive resins, beryllium oxide ceramics, aluminum oxide ceramics, and other small materials, as well as the contact thermal resistance at solid interfaces and the thermal conductivity of the materials. The materials to be tested are usually in solid, sheet form, and can also detect powdered and paste-like materials with the addition of a frame.
