Product Information:

Thermal Conductivity Tester adopts the internationally recognized hot plate method for measuring thermal conductivity and thermal resistance. It features computer-controlled fully automatic testing, generating comprehensive experimental reports. The instrument is suitable for testing the thermal performance of low-thermal-conductivity materials such as insulation materials and refractory materials. With an additional sample frame, it can also test powder materials. It is widely used in universities, research institutes, quality inspection centers, and industrial enterprises.
