MACHEREY-NAGEL pH Test Strips Editorial Review
The Macherey-Nagel 92110 pH indicator strips are designed to test liquids and can be used to test the pH in cheese or rainwater for house plants. They are accurate for testing water-based shampoos and conditioners, but not oils. To accurately read the results, the corresponding colors on the strip should match the colors for a specific number, but one user expressed confusion and stated they would not reorder. These strips can last for several years if kept in a dry, cool place. The pH range covered is 0-14 but may not be sensitive enough for certain applications such as testing body pH through saliva.
