Universal pH Test Strips 0-14, Quick Reliable pH Testing Kit for Water, Soap Making & Kombucha, 125ct Litmus Paper pH Test Strips for Liquids, Drinking Water, Aquarium, Pool, Hot Tub, Spa

Easy to use & refer to chart.

I've used them a half dozen times and they are easy to read and seem to work well.

A bit hard to see slight color differences but works well enough.

These testing strips worked sooo good for my child’s science fair project !!. We did a water filtration system and It was very accurate !. Very inexpensive and easy to use !!

I have been using these to test the Ph acidity of our fermented chicken feed. I don't find them difficult to read at all. They are easy to use and the color is right on the money. You get a lot of them and they are a great value. So far they seem to work pretty well and I will be ordering some more.

These things are garbage. You get pretty colors on strips of paper but it doesn't line up with the chart it doesn't tell you what each line identifies it doesn't give you any instructions on how to improve the levels. You get zero information which is absolutely not helpful at all.

Presumably accurate to the integral numbers (ph4, ph5, ph6 etc.) but in my case I needed to know if my canned salsa was above or below ph 4.6 (the level below which Clostridium botulinum cannot survive) and the color matching was not as clear as I needed. Should have spent the extra bucks on s ph meter. If you don’t need that accurate a measurement this is a good way to go,

Works well when I am making my homemade vinegars. It is easy to read when they get to the right acidic level.

Lässt sich sehr gut ablesen. Gefällt mir. Schnelle Lieferung

Great speedy delivery, the bottle had a great seal

Scheint zu funktionieren

Good for giving a easy to read Ph value. Thank you.

I was looking for a practical and cheap solution to assess the acidity of the soil in my garden. Read about using pH strips in a settled slurry of soil mixed with distilled water. I sued these strips and validated the results with a conventional soil test kit that I had. I helped verify my soil was too acidic (which match other parameters). Saved me from buying a digital pH meter and a set of calibration solutions (overkill for my needs!).
