Easy to use & refer to chart.

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.

Works as expected but can’t read accurately by only comparing colors code.

Immediately tested against dollar tree "awesome" cleaner. Heavy alk as expected. Plan to verify neutrality for ultrasonic cleaning solution on a project soon; will update if any issues arise!

Did Not Work for My Needs I purchased these strips to measure the pH of my cosmetic products, but unfortunately they did not give accurate or reliable readings. I tested several fresh strips and many showed inconsistent colors, even before being dipped into any liquid. They may work for other purposes, but they did not work for cosmetic formulation.

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 !!

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,

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