Laboratory TDR Probe

LP/ms Laboratory TDR Probe

LP/ms is a small laboratory TDR probe for the measurement of moisture and salinity (by means of bulk electrical conductivity) of porous bodies, especially soil. Its size and shape is designed to fit into cylindrical containers and enable testing small samples. It can be used for monitoring the changes in water and salt distribution in soil columns or in soil cores sampled with standard sampling equipment. Several LP/ms probes can be inserted through the side wall of a soil column or a steel sampling cylinder, thus allowing for vertical scanning of the instantaneous moisture and electrical conductivity profiles. Such an array, when combined with similarly installed minitensiometers LP/p, enables collecting a set of corresponding water content and matric potential gradient data from drying or wetting front transition. This allows for determination of a complete set of the soil unsaturated water flow characteristics, i.e.: water retention (PF-curve), water conductivity (k-function), differential water capacity and unsaturated water diffusivity.
