Indigo® pH 7-14 pH test strips detect weak to strong alkaline solutions; only $13.75/100 strips. Ideal for strong bases such as NaOH (lye) up to weaker bases such as milk of magnesia.
Compare all 3 pads to the color chart. The closest match of all three is the correct value. Only one or two of the 3 pads will change for any given base.
