Has anyone had trouble with their Conductivity Meters getting wet from inside?? We had several that lost calibration and when we opened them up they were wet and could not be calibrated.
Any suggestions??

I have seen one with a cracked cup before. I would make sure that the bottom is sealed back in place and it is dry after calibration.

Have had mine for a year now, and no problems noticed (I opened it up after reading your post)

good luck!
