So I recently started using the TF-100 and the pH test it comes with is the basic kind where you put 5 drops of indicator and match the colors. Same setup I had with my old Taylor kit from Leslie's. I have a "cheap" pH meter that I use for brewing that I needed to calibrate the other day so I figured I would check my pool's pH with that since it was already out and I happened to be testing my pool water. The results where not the same as the indicator test results. Meter shows 7.3 and the drop test shows 7.8. Obviously we're not talking about a huge difference here, but I was just curious which of these two methods is more accurate? The meter I have is the Checker by Hanna.
