pH 4.5-10 , 3 Pad Test Strips [Bag of 50 Strips]

Description

The pH 4.5-10 test strip is a medium-range strip measuring in steps of 0.5 pH units, containing three pads for enhanced accuracy and results in just seconds. The pH 4.5-10 test strip is ideal for testing slightly acidic to slightly alkaline solutions.

When comparing to the color chart, the closest match of all three is the correct value. Only one or two of the three pads will change for any given acid.

Instructions:

1. Remove one pH 4.5-10 test strip by holding between your index finger and thumb. Do not touch the test pad with your finger.
2. Dip the test strip into the solution to be tested so that all three pads are completely immersed.
3. Remove the test strip, and shake off any excess liquid.
4. Compare to the color chart within 30 seconds. Do not allow the test strip to dry before reading against the color chart.
