Hello
I have a nice digital pH meter by Thermoworks. I recently noticed discrepancies between the digital meter and the Taylor color match test. I’ve calibrated my meter in the buffer solution and then got a reading of 7.68 on my pool water. Seems perfect. When I did the color match test, my eyes see it at about 8. Which result should I be trusting? It seems to me that the color match test is “fool proof” while the digital meter has room for user error.
