Several months ago 1 of 2 of my ph probes has been giving erratic readings at all times of the day. One minute it may read a normal 8.2 and the next it will jump to 18.5 and stay there for several hours or days. Sometimes it will read 3.5 and again stay there for several hours or days. The other probe works just fine.
I've switched the probes in their ports to make sure it wasn't a bad probe. Probes were only a couple months old when this first started happening.
Just recently the other probe started doing the same but not as frequent and also my temp probe has been acting funny. Just last night the temp probe read 212 instead of the normal 79.
Should mention that if i do a power reset the probes will start reading correctly until they freeze again.
Any suggestions?
Thanks
