Tpl-III Thermal Conductivity Tester (Heat Flow Method)

The instrument is mainly used to test thermal resistance of thin thermal conductors, solid electrical insulating materials, thermal grease, resin, rubber, beryllium oxide porcelain, alumina porcelain and other materials, as well as contact thermal resistance at the solid interface and thermal conductivity of materials. The detection material is in the form of a solid sheet, and powder state material and paste state material can be detected by adding a frame.

GB/T 5598-2015 Test Method for Thermal Conductivity of Beryllium Oxide Ceramics
GB/T 29313-2017 Test Method for Thermal Transmission Properties of Electrical Insulation Materials
ASTM D5470-2017 Test Method for Thermal Transmission Properties of Thermally Conductive Electrical Insulation Materials
 

The model TPL-III Heat Flow Method Conductivity Tester is designed and manufactured as per the standard ASTM D5470-2017. With more than 10 years experience of manufacture and feedback from users, we continuously develop and improve performance of the product. Equipped with servo motor, automatic thickness measuring device, the instrument can precisely and automatically control pressurization, and full automation can be achieved when the instrument is connected with a computer. The instrument adopts 6-point temperature gradient detection to improve accuracy. A heat protection device is added around the test rod in the test head to protect the sample from heat, which reduces the influence of the ambient temperature on the test. It can detect thermal resistance curves under different pressures, and adopts optimized mathematical models to measure multiple parameters such as thermal conductivity and thermal resistance of materials and contact thermal resistance at interfaces. Adopt the latest technology to automatically compensate the temperature of the cold end, and no need to add ice water compensation device.
Users can choose standard or smaller models (with the same performance) to save laboratory space.
It is widely used in the thermal conductivity analysis and detection of materials in colleges and universities, research institutes, quality inspection departments and production plants.
