💡 What is a handy way to use pH paper strips for quick testing? This handy guide helps you get reliable readings fast.
- Dip a fresh strip into the sample briefly, then remove and wait for the color to develop for an acid-base reading
- Compare the resulting color to a reference chart to estimate the approximate pH range
- Use a new strip for each sample to avoid cross contamination and confirm accuracy
- Record the pH value for documentation and future testing
