What’s the most accurate way to measure PH?

[NtxMelanie]

Is there a more accurate way to measure PH? I have trouble reading the daily test kit color that came with my TF-100. I know I can measure TA but I didn’t know if there was a easier to read way of measuring PH.

Why does your pH test need to be more accurate?

pH anywhere in the 7s is equally good.

There is no prize for hitting a specific number.

There are digital meters that IMPLY better accuracy but they require frequent calibration and the cheaper ones don't seem to perform as consistently like you would hope. That R-0014 is Phenol Red and over the years has proven to be dependable......just a little hard to read.

TFTestkits has an $18.00 meter that seems to be dependable enough if you feel you want the extra precision it provides

I look for a slight orange tint and add acid when it's obviously a deep red.

Thank you, that’s helpful! I cant figure out if it’s at 7.8 or 8.2 but it’s def more red. I will try a small dose of Muriatic acid this evening and see if the color turns more orange

Thank you, I will try that if I keep having trouble. I’m pretty sure I’m a little bit colorblind and that really doesn’t help with pool testing

Try holding the color block sideways or upside down. Sometimes that helps me discern the color better.
