SKIPPER non-destructive moisture meter provides a complete, safe method for detecting excess moisture in GRP and wooden boats. Three scales of sensitivity allow moisture detection in salt or fresh water.

How it works:

  • The Skipper moisture meter detects moisture in wood or GRP (Glass Reinforced Plastic) by measuring the resistance between two low frequency AC signals transmitted from the soft rubber electrodes on the base of the instrument.
  • Because salt water is more conductive than fresh water, the Skipper is fitted with different ranges of sensitivity to allow testing of wood or GRP in either fresh or salt water environments.
  • Simply select the correct scale:
    Scale 1: Moisture in wood in fresh water or GRP in saltwater
    Scale 2: Moisture in GRP in freshwater
    Scale 3: Moisture in wood in saltwater
