Fishie February 19, 2012 Share February 19, 2012 I have a ph probe on my apex and it's been showing what I think is a higher than normal ph of 8.8..it's about 2 yrs old I got some calibration liquids...what's the process to recalibrate it or verify if it is showing me the right ph.. Do I dip it directly in the calibration liquid or take some out of the bottle. Link to comment Share on other sites More sharing options...
