Year: 2020 Language: English Author: Jeffrey Casciani-Wood Genre: Shipbuilding Publisher: IIMS Format: PDF Quality: eBook Pages count: 36 Description: The first thing to know about moisture meters is that they do not actually measure moisture. What they do measure is conductivity. The origins of the moisture meter lie in the building and construction industries and the original scale was based on the water content of brick and stonework. The scale has largely remained unchanged. There are a number of these machines available in the market and they were first introduced into the marine industry for checking how an frp hull had dried over time prior to rebuilding for osmosis treatment and for that they remain a useful tool. They are also used to check for moisture below a surface that looks dry. Electrical moisture meters have an enormous advantage for the general survey as they are clean and nondestructive, but they do have limitations and they do NOT quantitatively measure moisture on/in hull substrates. The majority record electrical resistance between two applied electrodes or capacitance and, more recently, some measure the reflection of radio frequency emissions from the meter.
