ORP probe

I had read a couple of weeks, and seemed to recall mine starting "low" and ramping up a few hundred mV over that period. Knowing now what my typical range would be between day to day operations including waterchanges (now) I think those first two weeks must have been that stabilization period.
FWIW
 
In my rare cases of using ORP I found it took the probes a week or so to work like my other probes.
