POnd master and digital meter always read 1 Ph higher than the test strips. But I use the test strip for alkalinity.


I suspected the 5 in 1 strip is inaccurate, particularly in PH readings.
No matter what I do, I can't get it to read above 6.5.
Hopefully the digital meter gives a true reading. I will compare it against the API
master kit.

I'll be thrilled if the digital meter reads 7.5 PH. That's an accomplishment for my area!
Clay acidic soil and pine trees!
Tobacco and pine trees are what grows well around here.
