I have two brands of pH strips
pHion and some from Indigo instruments
pHion
2 colored squares
range 4.5-9.0
.25 unit increments
use for saliva or urine
Indigo Instruments
3 colored squares
range 1-14
1 unit increments
from a science store
My pHion strips read my water in the hydro solution at 5.5 while my Indigo strips read a solid 6, maybe even towards 7...
solution? should I get a electrical pH meter?
