A description of a microprocessing instrument that measures 
the time of capillary soaking and the cosine of the wetting angle 
at a horizontal position of a porous body is presented. Determination 
of the wetting angle and kinetics of capillary soaking is based on 
approximation of the solution of the differential equation of liquid 
flow in a capillary with account for evaporation.
