Product Description
pH 2-9 Test Strips, 3 Pad
The pH 2-9 test strips contain three pads for testing accuracy. This strip measures in steps of 0.5 pH units, and gives results in just seconds. pH 2-9 test strips measures a wide range of both acidic and alkaline solutions. This strip can be used to test cosmetics and other acidic to weak alkaline solutions.
Instructions:
- Remove one test strip by holding one of the test strip between your index finger and thumb. Do not touch the test pads with your fingers.
- Dip the test strip into the solution to be tested so that all three pads are completely immersed.
- Remove the test strip, and shake off any excess liquid.
- Compare to the color chart within 30 seconds. Do not allow the test strip to dry before reading against the color chart.
NOTE: 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, and they will read differently in varying lighting conditions (incandescent, fluorescent, sunlight).
