pH 1-14 Test Strips (Single Pad)
The pH 1-14 test strips (single pad) are wide-range strips measuring in steps of 1.0 pH units, and give results in just seconds. Use wide range pH 1-14 test strips (acid-base) when you have a diverse range of materials, and you are unsure what end of the spectrum you will land on. This strip has one pad for ease of reading and can be used in many different circumstances, including education, industry, cosmetics, water testing and more.
Remove one test strip by holding the test strip between your index and thumb finger. Do not touch the test pad with your fingers.
Immerse the test strip about 1/2″ into the solution to be tested for 1-2 seconds.
Remove the test strip, and shake off any excess liquid.
Compare the test pad to the color chart within 30 seconds. Do not allow the test strip to dry before reading against the color chart.
