corrosion meter
Posted by jklingel on Mar 11 2005
I am just learning about galvanic corrosion on alum boats. Apparently one SHOULD have a meter and keep the voltage (between boat and water) between 0.9 and 1.1 volts. Less or more will generate pitting of the hull. A tube that "reads" the salt water costs about $100 (I have their url, if interested) and you can then use your multi-meter for measuring voltage. I am curios about what (if anything) people do to keep the crap from growing on or eating their hulls up here. Apparently Whittier folks don't give a fat rat's! Odd. Hulls are not cheap. j
