Discussing the measurement of the thermal conductivity and resistivity of soil and concrete using the transient line source technique. The transient line source (TLS) is an ideal and standardized method for testing materials in-situ and in the lab. Thermtest’s TLS-100 thermal conductivity meter is an easy-to-use and affordable instrument used for testing soil, rocks, concrete, and polymers.
Dr. Daniel Cederkrantz is an expert in thermal conductivity with a focus on transient methods. He is a graduate in Engineering Chemistry with Applied Physics and a PhD in Material Science from Chalmers University of Technology in Sweden. In 2018, Dr. Cederkrantz transitioned from the CSO at Hot Disk AB to the CEO of Thermtest Europe AB.
