How to Use a Tramex Skipper Plus Meter

The Tramex Skipper Plus moisture meter helps boat owners monitor the condition of their boat from one season to the next. The Tramex Skipper Plus is primarily for use on boats with hulls made from glass reinforced polyester (GRP). The meter will determine if water is being absorbed by the GRP, and will help you make the best decisions on which maintenance techniques are best for your laminate.

Instructions

    • 1

      Wash the hull thoroughly with a pressure washer and allow it to dry prior to taking the reading. Slime, seaweed and salt will retain moisture and lead to inaccurate meter readings.

    • 2

      Empty, rinse and dry the bilges. Choose a day that is dry because humidity will affect the reading. Do not take readings in subzero temperatures.

    • 3

      Set the Tamex Skipper Plus to the range which meets your requirements. Range 1 is for teak hulls and Range 2 for GRP hulls, while Range 3 is for measuring surface moisture on any hull surface.

    • 4

      Remove the surface coating only if it is an electrically conductive material such as Copperbott or Graphspeed. Clear two small areas where the electrodes will go. If your coating is not electrically conductive, you can simply place the electrodes against the hull.

      Take your readings. Use the Percent H2O scale rather than the relative scale. Take readings on several points around the hull.
