Identify osmosis problems before blisters appear
Identify wet cores in sandwich or cored structures
Monitor hulls for drying before repairs and osmosis treatments
The Tramex Skipper 5, SMM5, is a dual-depth, non-destructive Marine moisture meter which safely detects excess moisture hidden in GRP boat hulls, decks and coach roofs including sandwich or cored structures. The unique three-electrode array provides both shallow (10 mm / 3/8") and deep (30 mm / 1 1/4") perceptivity to help establish the depth of any moisture within GRP composites. In addition to the classic moving-coil display, readings may also be sent to the free Tramex App on paired Android and iOS devices. Pocket-sized and specically designed for GRP the Tramex Skipper 5 is self-contained, easy to use and ready to go, needing no user calibration.
GRP composites and hardwoods are non-conducting materials, nevertheless their electrical properties change with increasing moisture content. The Skipper 5 determines moisture content by applying a high-audio frequency signal between a pair of soft rubber electrodes on the instrument base. A third electrode provides genuine shallow range measurements on a smaller footprint. Capacitive coupling between the electrodes and the sample allows impedance to be determined. This is interpreted as a moisture value and displayed on a large, clear moving coil meter. Additionally, meter readings may be sent instantly to a Tramex App on Android and iOS mobile devices by Bluetooth.

Effective osmosis treatment requires the complete removal of the hygroscopic solutes that are responsible for absorbing and retaining moisture and forming osmotic cells in GRP composites. Featuring both deep and shallow modes the Skipper 5 is the ideal instrument for locating moisture associated with these solutes to help ensure successful treatment. Marine timbers also suffer from excessive moisture which causes blistering and loss of paints and varnishes. Trapped moisture encourages fungal growth and black fungal staining. The Skipper 5 enables quick surveying over moisture over large areas, will read through paints, varnishes and sheathing such as Cascover without causing damage and may be used to find and trace leaks above and below decks.
