Introduction

There are many things, all around us. Among them are things which easily conduct heat and those which do not, and we select the appropriate materials for how they will be used. The thermal conductivity rate of those materials is not only important for science and engineering, but is a fundamental physical value with which our daily lives have an intimate relationship.

What is thermal conductivity rate?

Thermal conductivity rate λ : Ease of conducting heat Thermal flow density when there is a steady temperature inclination

Unit: W/m・K (watts per meter Kelvin) *Before becoming SI unit, this was often expressed as Kcal/mh°C

What kinds of devices are there?

Among the methods of thermal conductivity meter are the constant method and the nonconstant method.

The KEM Thermal Conductivity Meter is classified in the nonconstant method.
