Indigo® pH 7-14 pH test strips detect weak to strong alkaline solutions; only $13.95/100 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.

  • The number of strips (100) per pack or vial is approximate.
  • Wide pH alkaline range pH 7.0-14; resolution is 0.5 pH unit
  • Minimum shelf life of 3 years if container kept closed but typically good for 5 years.
