It seems that a larger issue should be addressed.  Why would the conductivity of
mud be interesting?  The conductivity will depend primarily on salinity or
ionization--not water content.  Conductivity can easily be measured with a
$20.00 voltmeter by inserting two wires along a common axis and measuring the
distance and resistance between, i.e., ohm-cm.
