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?
