Electronic moisture meter operate on the principal of non-destructive impedance measurement of moisture. Coplanar electrodes are fitted on the base of the instrument from which low frequency signals are transmitted into the testpiece, measuring the change in impedance caused by the presence of moisture. This reading is translated by the instrument into a moisture content reading on a relative scale.


Moisture content.

Osmosis detection & treatment supervision.

FRP Sandwich
Water ingress detection & mapping.


There are some limitations with all moisture meters. Meters cannot detect moisture in the substrate through damp antifouling, and certain types of filler prevent reliable readings.
Carbon fibre laminates being conductive prevent the use of moisture meters
