I made something like that for my saltwater tank a few years back. It cost me a few bucks, and it also used two wires that were a few millimeters apart, and when the water evaporated, and left the wires dry, the alarm sounded. It could easily be modified the other way (alarm sounds when wet). Costs a few bucks to make. Only problem is that it wouldn't work in pure RO because there are (theoretically) no ions present in the water which would "carry" the electrons from one wire to the other (or in layman's terms, the connection wouldn't be closed, and electricity wouldn't flow).
