pH Test Strips,5 Packs of 400 Strips pH 1-14 Test Paper,for Urine,Saliva,Drinking Water,Pool,Spa,Soap,Fish Tank and Liquids

Made very cheap, but they work very well for how cheap they are, it is worth the price!

This product is easy to use, covers a very wide range of pH, and seems quite economical. So far, so good. It remains to be seen if the shelf life is limited. Pleased this far.

I bought these to test my alkaline water system to make sure of when I need to change the filters. I also tested our alkaline system that my boss (a doctor) installed in our office. Both systems test to be at least 8 on the pH scale. These come in very handy because it’s important to know if the systems are functioning properly.

It works but easily degrade when I opened it but found by wrapping it wit foil it last longer

I purchased this for my students in addition to the red and blue litmus paper. What I love about these strips(unlike the red/blur litmus paper) is that the students were able to see the different "levels of color indicators" appear to help them have a better understanding of (weak/stong) acids and bases of food and household items!Although they enjoyed using the red/blue litmus papers, they had more fun with using these strips!

I thought I'd keep it simple by getting actual test strips, but that was a bust. Guess I'm gonna go back to my digital pH tester I'm wondering if they'll except returns after four strips have been torn out?

Cold process soap making.

I have tested several different waters including our tap water and everything gets the same rating????not sure how this could be right!

Quick and easy to use. Good price point

Small tear off strips, very easy to use.

Its more suitable if you want to know if a liquid is generally acidic or alkaline, but its not designed for an accurate rating.

I tried it on water and vinegar and the strip does change color according to the pH, but I am not sure how accurate it is. You have to compare the color before it drys out, otherwise the color changes back.

The strips didn't work as described. No change in colour at all, even on highly alkaline or acid.Very disappointed.
