I have a
American Marine Pinpoint pH Controller
and was wondering the accuracy of these things. From what it says, I have a ph of sub 6.0, but my ph test kit says differently. I just calibrated this controller last week.
The probe is brand new,
I calibrated using 7.0 and 10.0 calibration solutions.
So anyone else have experiences with the controller?
I'm eventually trying to automate my CO2 injection but since I see that my pH is staying this low, I have strayed away from injecting any CO2 and just sticking to excel doses.
