What are the two types of thermal conductivity meter?

The two types of thermal conductivity meter are steady-state and non steady-state, also called transient. Steady-state are more suitable for precise, controlled environments where accuracy is critical while non-steady-state or transient methods are ideal for quick and versatile assessments.
