Probes were constructed to measure non-destructively the moisture content of soil in a pot. The thermal conductivity of the soil was determined using a line-source of heat which yielded measurements ...
TUCSON, Ariz. — A fork-like conductivity probe has sensed humidity rising and falling beside NASA’s Phoenix Mars Lander, but when stuck into the ground, its measurements so far indicate soil that is ...
Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...
