Plastic pH Test Strips, Universal Application (pH 0-14), 100 Strips | for Saliva, Soap, Urine, Food, Liquids, Water with Soil Testing, Lab Monitoring, etc.

Used them to test my homemade vinegar yesterday. It works! Easy to read. My vinegar ph level was 3

Accurate, easy to use and read results, very reasonably priced and not expiring for over a year which is great! Very good product for testing my well water!

Exactly what the description explained and it was what I needed..

They work well to see the pH level. But I needed a different range of pH.

I’m not really sure how to use these or if they are accurate. Apparently, there are several colors in each row that you maybe are suppose to try to match. More colors that you never thought of. All guess work as there are no instructions. F for expecting user to know how to use. The plastic container they are presented in is also an F as pulling one out and even pulling top off causes more to come out of container, with goal of not getting other strips contaminated after they fly out all over your bathroom or wherever one might be when using them. Again, another poorly designed product - over priced at that.

Works great and easy for my students

they work

My fifth grader informed me about the science fair project that was due, 2 days before it was due. 😑 I bought him these and he was able to test the pH of various drinks and make a little poster about dental health.
