The pH 11.5–14 test strip is used to test the pH of narrow-range solutions in increments of 11.5, 12.0, 12.5, 13.0, 13.5, & 14.0.

pH 11.5-14 Test Strip
- Remove one pH 11.5-14 test strip by holding one end of the strip between your index and thumb finger. Do not touch the test pad with your fingers.
- Dip the test strip 1/2″ into the solution to be tested for 1-2 seconds.
- 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.

Product Documentation
Does temperature affect the pH test strips?
Our pH Color charts were developed using NIST-traceable pH buffers at 25°C. Colorimetric pH test strips do not offer “temperature compensation.” Care should be used when comparing results using test strips to those obtained with a temperature compensated pH meter. It is well established that the “true pH” of a solution will be influenced by temperature. The extent of the effect is specific to the solution being tested. It is good practice to record the temperature of the solution when expressing results of pH testing. In the case of test strips, since they do not compensate for temperature, it is recommended that the sample being tested be brought to room temperature first.
Can I use pH test strips in non-buffered or low-buffered aqueous solutions?
Currently, our pH test strips are designed for testing buffered solutions, and the calibrations (color charts) are made on buffers against a pH-meter measurement. For non- or low-buffered solutions, these strips are not suitable. For this purpose, there are special pH test pads designed for low-ionic and low-buffered waters, such as water in aquariums or pools. Please see our Aquarium and Pool test strips.
