Product Description

pH 5.5-8 Test Strip

The pH 5.5-8 test strip is a narrow range strip, with steps of 0.5 pH units, and gives results in just seconds. The pH 5.5-8 test strip measures in smaller increments (0.5 pH units) than our pH 5-9 test strip. The pH 5-9 test strip also has a color range that includes blue on the upper end of the scale.


  1. Remove one pH 5.5-8 test strip from the bag, holding one end of the strip between your index finger and thumb. Do not touch the test pad with your fingers.
  2. Dip the test strip about 1/2″ into the solution to be tested for 1-2 seconds.
  3. Remove and shake off any excess liquid.
  4. Compare immediately to the color chart. Do not allow the test strip to dry before reading against the color chart.
