Soverign Moisture Meter : Fully operational moisture meter suitable for measuring the moisture content of GRP hulls. I purchased this when i was treating a hull for osmosis. This is the model that my surveyor had. I used to follow the progress of the drying activities. A must if you want to check the progress of treatment or just a keep a eye on how much the hull dries over winter out of the water. An excellent piece of kit.
