I have the TF Pro and added the pH meter option but still can't seem to get conclusive results. Based on visual pH test, I'd say I'm at/around 7.5; however, the pH meter read 7.9 today. I have calibrated the meter using the test solution but for some reason still don't fully trust it. How important is it to know exactly what pH is? Am I okay as long as I'm within a certain range?
Accurate pH?

Trust the visual drop test.
Any pH in the 7's is ok.

With everything else in normal ranges Trust the drop test over the meter. It is the standard.
That meter may just be wonky & need to be replaced in which case contact tftestkits for a refund or replacement.
What are the rest of your test results? High fc levels (10ppm+) can skew the ph drop based test.
As Aj said - ph in the 7’s is fine

Some have reported the less expensive meters being affected by battery level so may try getting a fresh one & recalibrating.
Recalibrated and its not the meter, its my eyes. pH meter captured both known substances spot on.
So with water at 7.9 pH, is it time for MA?
