WARNING pH monitors too close.

Just a warning to those who use constant diplay monitors. I had mine on the canopy of the tank so I could see it easily. It quit working right, and started giving me strange reading.......the probe is way past due for replacement, so I went and spent another 40 bucks on a new probe...........still didn't work, so I popped it open and found this. Just thought I would warn you guys to either seal them yourself somehow, or keep them in a dry area where saltwater won't corrode them. Sucks losing anything when everything costs so much. It was there for about three years.

Is that a Pinpoint?

It was a pinpoint anyway. I soldered a few broken connections after I cleaned up the corrosion, and now it reads only -1 ??????? Anyone understand what might cause it to only give the reading -1 ?

You must have a short somewhere. After having an overflow accident with mine, it wouldn't read, so I rinsed it thoroughly with alcohol and let it dry out. Until it was totally dry I got a -1 reading as well. It works now, and I moved it.
the -1 seems to be it's "error-somethings not right with me" message

Also could have damaged some of the components with all of the high resistance paths. Make sure you rinse it off well with some alchohol and let it dry for a day. You could use DI water, as it shouldn't harm anything either, but only if it is lab quality.
