So I took a spare PH probe and calibrated to a Pinpoint monitor (don't like the Apex calibration).Hmmmm....
So you think my PH monitor is inaccurate.
I will concede that I have not calibrated the probe in awhile.
I will get back to you, in a few...
It needed minimal adjustment at either 7 or 10. I went for slightly lower.
As of 2pm the Apex probe read 8.4 while the probe attached to the Pinpoint stabilized at 8.15 and is now at 8.17
