Pack of 2 PH 1-14 Test Paper Litmus Strips Tester, 80pcs Per Pack

These pH test strips are a convenient and affordable way to measure the pH level of various substances. The wide pH range of 1-14 makes them versatile for testing water, soil, saliva, and more. The strips are easy to use: simply dip them into the solution and compare the color change to the provided color chart. The results are fairly accurate and provide a quick overview of acidity or alkalinity. While they may not be as precise as laboratory-grade pH meters, they’re perfect for general testing and educational purposes.

I just threw away two more pH meters. I'm done with meters. I'm happy with the pH testing strips. It's less hassle. I don't have to calibrate paper or wonder if the paper is accurate like the meters.

I used these to measure the acidity in vinegar I made. And I mean, they work, but it’s truly hard to tell if the color on the strip is because of the acid or because of the color of the liquid (this was raspberry vinegar). Perhaps this is a problem with a strip and not some sort of device, but I found these to be more of a guessing game than I expected. Still I felt that the vinegar seemed alright (the strip didn’t turn blue) so I bottled it and went on to make delicious dressings. So these work but they are certainly more of a guessing game than I’d like. For the money, I think it’s a good deal and maybe this will work better for folks not testing already colored solutions

They’re inexpensive litmus strips. They’re very bright when they change color, so the activator chemical is definitely soaked in really well, but you can’t really read anything but whole numbers for the pH... not a lot of subtlety between reaction colors. Great for the money, though 👍🏻

If you want to measure the pH with a resolution >2, these work ok. e.g. If you are trying to distinguish a pH reading between 4 or 6, this will work. But it is difficult to distinguish between a reading of 4 or 5, or 7 or 8.

I got this to test my homemade gesso and hand mixed paints. I do a lot of mixed media art on a big variety of materials. Having a ph neutral from homemade stuff is rather critical. Acid destroys art in a very short amount of time. It was tricky to understand the chart. However, I figured it out after I tested vinegar for acid, tap water for something close to neutral, and baking soda mixed with water for the base. I am a geek, but hey I save money that way. It works for what I needed it for. It will be critical when I start working with coffee art. Coffee is beautiful for painting with, but is it ever problematic with paper.

You get a lot of test strips for a very little amount of money -- excellent value! I don't have a known accurate pH meter to compare these test strips to so I can't comment on their accuracy. However, I created an acid bath and sure enough, the strips said it was acidic. After I was done using the bath I neutralized it with a base and this was reflected in subsequent testing as well. I also tested our tap water which is from a well and it was about 9 which seems reasonable. I would trust these strips for projects where you don't need precision (in which case you probably shouldn't be using testing strips anyway).

I got these to test my soil and water and they are so helpful! I was having no success eliminating itchy poisons permanently like in previous years! When I tested all of my water, even hot, the Ph was only about the same as urine, a 6 or 7. Since then, I have washed my calamine, oat wash, glue solution into the sinks several times per day, not only in the shower like before, and double or triple boiled my water. Finally, the Ph is now going up to 9 and 10. I am trying to get a 14!
