WebThermal resistivity testing of soil and concrete materials using ASTM D5334 or IEEE 442 standards require a minimum sample size of 11cm in length and 5cm in diameter. For disturbed soil samples, a gallon bag of material is plenty. Fluid samples only require 200 mL. WebThe Soil Conductivity Meter is a portable thermal conductivity meter used to measure thermal conductivity and thermal resistivity. Perfect for testing the thermal conductivity of soil, polymers, viscous liquids, and other soft materials; as well as testing the thermal conductivity of concrete, rock, stone, or other hard materials.
WebOther users talk about the thermal resistivity. The latter is simply the inverse of the thermal conductivity in m·K/W. There are standards for measurement of soil thermal conductivity.
