Speaking of Weston and GE meters and Metrawatt, I dissent. I have never
encountered anysuch which has failed from this semi-mythical "moisture"
problem. And, again, George Milton and the other repair guys I have spoken
argue that sealing after WWI was pretty good and that the most common cause
of failure was breakage in the mechanical links.
"Most common", no. An occasional problem, sure.
