This product contains two packs of 100 pH strips, 200 strips in total. Each strip is made of premium grade litmus paper intended for universal application. To test the pH of a solution simply dip the pH strip into your solution and the strip will change color. Quickly match this color against the color chart provided to obtain your solutions pH. Please see our infographic or scroll down for a list of common uses and examples of pH. To further the reliability of our products we randomly test each shipment we receive across multiple pHs to ensure product quality.
1. Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately.
2. Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait or let the strip dry!
3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral.
Please note that solutions with a pH of ~5.5 will result in a yellow colored test strip that resembles the original color of the dry strip.
Store in a cool, dry place away from sunlight.

I came back to amend this review because the pH test strips are not accurate. Tested against a calibrated meter and other brands of test strips they consistently read 2 points lower than actual, so an actual 9 pH water sample reads 7 on these test strips.This was true for both packs I received. It was not just me, I asked others, without prompting, to tell me what reading they perceived on the strip compared to the included chart and they agreed with my matching of the colors.
Purchase was from LabRat Supplies, fulfilled by Amazon, as some seem to be having some issues with observing any changes.
pH color scale is inside the booklet. You have to keep the booklet open when checking pH and the entire bunch of strips is exposed to accidental spilling.
Poor paper sensibility.
