Abstract

1,233,402. Measuring moisture content electrically. NATIONAL RESEARCH DEVELOPMENT CORP. Aug.20, 1969 [June 17, 1968], No.28774/68. Heading G1N. Portable apparatus for measuring the moisture content of a wall comprises an r.f. oscillator connected to electrodes 13, 14 for placing in contact with the wall and a meter 7 for measuring the power consumed by the oscillator. Additional electrodes 16, 17 may be switched in to change the measuring range.
