pH Test Strips, Universal Application (pH 0.0-14.0, 0.5 pH Intervals), 100 Strips

Description

This product contains one case of 100 pH test strips that are specially formulated to read a solution s pH down to the nearest 0.5 pH unit - more accurate than typical pH strips that read to the nearest whole pH unit. Each pH strip has four pieces of pH paper that will change color after being submerged in a solution. Each piece of pH paper has its own pH range and will change color accordingly. After submersion, the strips can then be compared against the color chart on the case to determine the pH. This method allows for fast and accurate pH readings.

Instructions:
1. Take one strip from the case and dip it into the solution you would like to measure. The colors of your strip will change instantly. Please note that not all two/four pieces of pH paper on your strip will change color - each piece has its own pH range and will change color accordingly. If testing saliva, do not put the strip into your mouth!
2. Quickly match these colors against the color chart on the front and back of your case to obtain the pH. Do not wait or let the strip dry!
3. The number above the matching colors on the chart is your pH. Any solutions with a pH beyond the pH range of your product will render inaccurate results.

Store in a cool, dry place away from sunlight.
