Introduction

This thermal conductivity tester adopts the internationally popular method of measuring thermal conductivity and thermal resistance using a heat flow meter, and is equipped with a computer to achieve fully automatic detection and generate experimental reports. The instrument uses a stable hot surface temperature added to one side of the sample, and heat is transferred to the cold surface through the sample. The heat transfer is measured to calculate the thermal conductivity and thermal resistance. Adopting imported sensors and computer technology, it has the characteristics of good measurement accuracy, high reliability, and good repeatability. Especially suitable for measuring low thermal conductivity (accurate to 0.1mW). It can be used for testing plastics, rubber, thermal insulation materials, aerogel plates, vacuum glass, etc., and is widely used in colleges, research institutes, quality inspection, factories and mines.
