Tramex Skipper Plus SMM5 Marine Moisture Meter for Fiberglass Hull Testing and Osmosis Detection

Tramex Skipper 5 Tramex moisture meter for boats — Boat-hull and deck moisture surveys

This moisture meter is aimed at marine surveyors, repair yards, and boat owners who need to locate elevated moisture quickly before making repair, installation, or survey decisions. Typical use cases include pre-installation inspections, damage assessment, maintenance surveys, and follow-up verification after drying or corrective work.

The unique three-electrode array provides both shallow (10 mm / ⅜") and deep (30 mm / 1¼") perceptivity to help establish the depth of any moisture within GRP composites.

The Viscosity Flow Cup Stand with Bubble Level is used by paint and coatings formulators, quality control labs, and industrial applicators to hold viscosity flow cups level for accurate measurement of liquid flow times. Proper viscosity measurement is essential in coatings and fluid quality control because uneven cup leveling can skew results, and industry guidance on standardized viscosity testing emphasizes stable setups for repeatable flow time readings.

Professionals value this stand for its simple bubble level and stable support that help ensure consistent, reliable viscosity testing. Compared with ad‑hoc setups, a dedicated stand improves repeatability and alignment with quality control protocols in paint, ink, adhesive, and coating workflows.

Features

• 3 Ranges of non-destructive sensitivity: Hard Wood / Shallow Depth / G.R.P
• Dual-depth penetration allows for a comparative of surface and core moisture to help establish the depth of any moisture within GRP composites
• Signal reaches up to 1¼" (30mm) in wood and G.R.P
• The shallow depth scale reaches up to ⅜” (10mm)
• Shallow-depth scale allows for a smaller, more precise footprint, similar to pin readings.
• A wide range of readings: 5% - 30% (Wood Scale) and 0 - 100 (comparative scale for G.R.P.)
• Bluetooth connection to accompanying IOS & Android Apps allows for Geo-taggeding, image-based documenting of moisture measurements.
• Hold Function allows to “freeze” the reading where the meter face is invisible.
• High Moisture audio warning signal which can be enabled or disabled.
• Large, easy-to-read analog display

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.

USES:

• Identify osmosis problems before blisters appear.
• Identify wet cores in sandwich or cored structures.
• Monitor hulls for drying before repairs and osmosis treatments.
• Check timber for excess moisture before painting, sheathing or varnishing.

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 of 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.

Application Q&A

What problems does this help prevent?

Proper moisture checking helps reduce failures such as flooring issues, hidden water damage, coating problems, or moisture-related deterioration in structures and boats.

Who typically relies on this type of meter?

Marine surveyors, repair yards, and boat owners rely on this type of instrument when they need quick screening and better decisions before invasive work or final sign-off.

Because it combines Detects moisture on boats, Soft rubber electrodes, High moisture audio warning tone, this meter is well suited to boat-hull and deck moisture surveys where quick diagnosis and repeatable surveys are essential.
