2 Pack pH Test Strips Universal pH 1-14 Litmus Test Paper 160 Strips for Saliva Urine Water Soil and Chemistry Experiments (2 Pack with Storage Case)

Strips work as expected

Great price and easy to use to test my tap water.

They seem accurate only use them 2x pretty good for the price and you get a lot.

They just work

It doesn't work. I've already tried it with my saliva, in liquid, and with lemon juice. But it doesn't change color; it just stays the same color. I bought it to check the pH of my saliva. The package was very nicely presented, the strips are too thin, and the color chart has very bright colors that are easy to see. But I couldn't verify it because the strips didn't work.

Only works for clear liquids. Won't work for testing canning goods

very affordable and easy to use. Covers full 0 to 14 pH range.

Great, works well and there’s a ph value chart too to match your strip color
