TRAMEX – SMM5 Skipper 5 Marine Moisture Meter – Dual Depth GRP & Timber Tester

TRAMEX - SMM5 Skipper 5 Marine Moisture Meter - Dual Depth GRP & Timber Tester

The Tramex Skipper 5 (SMM5) is a precision marine moisture meter engineered for boat hulls, decks, coach roofs, and marine timbers. With its dual-depth, non-destructive capabilities, the Skipper 5 identifies moisture problems hidden in GRP composites and hardwoods without damaging the surface.

Equipped with a unique three-electrode array, it detects both shallow (up to 10mm) and deep (up to 30mm) moisture levels, making it ideal for monitoring osmosis, wet cores, and trapped water in marine structures.

Readings are shown on a classic analog display, with Bluetooth connectivity to sync results with the Tramex mobile app for Android and iOS.

Key Uses:

• Detect osmosis in GRP hulls before blisters form

• Locate wet cores in sandwich/cored structures

• Check drying progress before GRP repair

• Ensure marine timber is dry before painting or sealing

• Trace deck and bulkhead leaks

Key Features:

• Dual-depth sensing (shallow 10mm / deep 30mm)

• Three dedicated measurement ranges for GRP and hardwood

• Wide scale: 5–30% for wood / 0–100 for GRP and others

• Audio warning for high moisture (toggle on/off)

• Hold function to freeze readings

• Reads through varnish, paint, Cascover, etc.

• Non-scratch soft rubber electrode pads

• Bluetooth app support for recording and reporting
