pH Test Strips, 4 Packs of 320 pH. 1-14 Test Paper, Litmus Paper pH Test Strips, pH Balance Test Strips for Women for Water Saliva Urine Soil Testing

We had an electronic pH meter before but it’s accurate range is limited around neutral. With pH paper, it’s a lot more accurate and easy to use. No need to clean oxidation anymore. This seller is also the best value I can find on Amazon. Very satisfied

I recommend this product. They are functional. The color rainbow on it works for the p.H. The ph level is true. Readability is perfect. I recommend this product.

Accurate Read, Easy To Use.

As you could see on the picture, it comes with colors but it doesn't tell you what each color means. So, it's useless.

I use these strips for my homemade products and they are perfect. It’s important for me to know the pH level of my products and these strips make it easy. I simply follow the instructions and get my results!

They fade a little bit but they work good and it’s great for the value. Used on wood floors it worked.

Everything I tried to measure the PH of showed the same color. Either every sample was the same PH (not likely) or they just didn't work.

I received my order of Ph strips earlier than expected.I tested them on vinegar, saliva and toothpaste, and the expected colors appeared. While not digitally precise, they are sufficient for testing whether my saliva is more or less acidic. And inexpensive!
