Abstract : A new portable instrum nt is described which is capable of detecting moisture in small concentrations in fiberglas r inforced plastics. Resonant circuits in a balanced bridge network determine empirically the change in permittivity and dissipation fac or of the ma eri l. A stable crystal-co trolled oscilla or po ers the bridge and measurem nt consists of placing a probeAGAINST THE MATERIAL, R ADJUSTING THE BRIDGE A NOTING THE IMBALANCE. (Author)
