2 Pack pH Test Strips, 160 Strips pH.1-14 Universal pH Test Paper Litmus Test Paper Soap Making Testing Strips for Water Wine Saliva Urine Soil Testing Pet Food and Diet pH Monitoring (Sealed Pack)

I purchased these for my son's science fair project. They worked really well!

Typical pH paper. Don't use these to read the pH of a pool as it will not work. The pool chlorine can chemically react with the pH indicator dyes on the paper and will not change color.

I love these test strips. I also purchased a digital ph tester and actually prefer these over the digital tester. Dip them in, watch the color change, easy peasy lemon squeezy. UNLIKE THE DIGITAL TESTER. Calibrate, if the instructions are clear enough to understand, then make sure you use the correct solution, then make sure the sponge at the top of the cap stays MOIST ALWAYS. Can’t dry out, so if you’re not using the digital ph meter weekly, you have to REMEMBER to moisten the sponge, yahhh like that’s going to happen!!! Get the strips MAKE YOUR LIFE EASIER

Ph value for most part is accurate but functionality is a lil iffy the rooms light or sunlight kinda changes it to where it’s hard to tell it says keep outta light which I get but kinda hard to tell the ph color then.

I bought these to test the Ph of skincare products, because my skin can get alllll angry if I'm not careful. These work almost instantly, it's a nice big test strip so easy to read, soyou're not squinting at the color chart, and they're a really good deal. I will probably not use even half of these before they expire, but I will buy them again when that happens.

Bought these to test the ph of my fish tanks before adding triop eggs and they worked perfectly and were very easy to read! Triops are extremely sensitive to ph and they hatched within 24 hours so id say these are very accurate strips.

These are super cheap and the paper is so dark, it's hard to tell what color you get when you use them. The color also drips off (watch for staining!) and fades really quickly. The included color reference chart really doesn't help at all. The strips might work better if the paper was white, since the chart is on a white background. I found these utterly useless and bought some plastic strips in a canister instead.

These universal pH indicator papers are easy to use and come in a handy matchbook-style pack, which makes them super convenient for quick testing while I’m making soap. The color chart is clear, and the strips seem accurate — I’ve gotten the right color range every time so far, and it matched the pH I needed perfectly. The reason for three stars is that the paper itself is very thin and could definitely be made thicker for easier handling. It tends to feel a bit flimsy when dipping into liquids. However, for the price, they do exactly what they’re supposed to and get the job done without any major issues.

A described. Good value.

These strips are convenient and work great. I recommend storing them in a plastic bag so humidity doesn't degrade them.

Pretty accurate and so many strips. This is perfect when you need to do a bunch of testing till you get ur mix right.

bought for my boy, he likes testing everything with it

They don’t seem to change color no matter what I test… maybe a faulty batch?
