3 Pack pH.1-14 Test Paper Extensive Test Paper Litmus Test Paper 240 Strips pH Test with Storage Case for Saliva Urine Water Soil Testing Pet Food and Diet pH Monitoring (3 PACK with Storage Case)

These I bought for use with my salsa and they function at the highest level. I bought an electronic one but like these better. They show the Ph easily and you could not find something easier to use, just dip it in the product. Storing them is easy as they are not that big.

It works well. Using for monitoring fermentation progress.

goodddd

It’s a good value, but they aren’t the best ph strips. The outer part being cardboard gets wet and eventually breaks up after doing a lot of comparisons. However, with how many we go through in a week—these are perfect for our application.

Strips work as advertised. Testing is easy and straightforward.

These came nicely packaged in a reclosable plastic box which was in a nice looking heavy plastic zip top bag. Unfortunately they do not work at all.I tested the strips in bleach, strong coffee and straight 5% vinegar. None of the strips changed color at all. They just got wet and darkened slightly due to the wetness.The instructions are obviously translated from another language, probably Chinese and not clear or understandable. From what I can understand, I think they're trying to say to test the solution using the center of the paper and read one second later. It also says that the paper "does not apply to buffer solutions and very weak acid-base solution concentrations lower than 0.01%". Not sure what they mean by an acid-base solution, but they probably just mean that the solution needs to be fairly strong and not diluted. I did not dilute any of the solutions in which I tried the test strips. I assume that what they mean by an acid-bsae solution, is either acid or base solution.Pretty disappointed.

works

It's a good strips but when you rely on something at specific time and it doesn't work it's disappointing. 1 pack doesn't work at all
