Accurate Testing for Informed Decisions.

The thermal dryout curve characterizes the relationship between thermal resistivity (rho) and moisture content in porous materials such as soil, concrete, or flowable thermal backfill (FTB). This analysis is critical for the accurate and efficient design of underground power transmission systems.
