BOJACK 5 Pack 80 Strips (400 Total) pH 1-14 Test Paper for Water, Soil, Pet Food pH Monitoring - Extensive Litmus Test for Various Applications

So my wife says to me " no wonder these plants aren't doing well, our water is acidic ". Well we live in the mountains and I know it is alkaline. She shows me a sample tested with some pool test strips and shure enough, it's acidic. Hmmm. Strips expired 2 years ago. Local store wanted 18 bucks for a test kit good for 50 tests. These new strips show slightly alkaline. This kit rules! Sorry honey, I was right (Again)

I used these with a group of 3rd graders as an extension project to explore alkalinity. They were super easy to use and the kids loved the autonomy they had with the project.

The product works just as you hope it would.

These absolutely did not work at all. I returned them as soon as I could!

Clear colors, cheap price, good quality

Easy to read and use

Decent product and does the job.

Plenty of litmus strips to tuck in my canning drawer. Unlike most people, I started out with pressure canning of meats, not water-bath canning of higher acid foods. Now that I'm good at the pressure canning part, I want to try water bath canning (which doesn't take nearly as long and doesn't cook the food to death in the process), but to do it I need a reliable way of determining how acidic something is and how much lemon juice or other acid I need to add to low-acid foods to make them acidic enough to safely can using the water bath method. Pam Cantrell of Rose Red Homestead (who I dearly love) recommended litmus papers for this purpose, so I got these.

The paper is porous. Can't identify the pH result, as it's next to impossible to identify in between which two colors it sits. It's like the color of the result doesn't belong anywhere at times. Tried to make sauerkraut. PH level was supposed to reach 4. Test says... is it 5? 4 and a half? But then you can't tell if it even is in between a 4 and a 5, like it failed or something. It helps a tiny bit putting white paper behind it, but even then.I then tried a different test that's made very different (not a digital one as I want to avoid having to deal with calibration). Right away a nice clean confident nearly 4 pH level.So while the other one was decisively clear, this one left me completely guessing, so I find these completely useless.
