TCT-3LP Thermal Conductivity Tester (heat flow method) (vacuum type)

Description

The TCT-3LP thermal conductivity tester mainly tests the thermal resistance of thin thermal conductors, solid electrical insulating materials, thermal conductive silicone grease, resin, rubber, beryllium oxide porcelain, alumina porcelain and other materials, as well as the contact thermal resistance and material at the solid interface. Thermal Conductivity. The detection material is in the form of solid sheets, and a frame can be used to detect powdery materials and paste materials.

Instrument reference standards: MIL-I-49456A (insulating sheet, thermally conductive resin, thermally conductive glass fiber reinforcement), GB5598-2015 (Method for determination of thermal conductivity of beryllium oxide ceramics), ASTMD5470-2017 (thin thermally conductive solid electrical insulation material Test standards for heat transfer performance), etc.

Features of the thermal conductivity tester: equipped with automatic pressure, automatic thickness measurement device, and connected to a computer to achieve fully automatic control. The instrument uses 6-point temperature gradient detection to improve test accuracy. It can detect thermal resistance curves under different pressures, adopt optimized mathematical models, and measure multiple parameters such as material thermal conductivity and thermal resistance, as well as contact thermal resistance at the interface.

It is widely used in material thermal conductivity analysis and testing in colleges and universities, scientific research units, quality inspection departments and production plants.
