Litmus pH Test Strips | (pH 1-14), Universal Indicator, 2 Packs of 100 Strips. Test and Track Your Water, Diet, Saliva, Pool, Aquarium, Urine, and Soil.

These strips are fantastic. They have a nice thickness to them, don’t fall apart or tear when taking them out of the pack or wetting them with the test material, and they seem to be pretty accurate. We received two matchbook sized packs and I had to hide one from my six year old who has decided to test EVERYTHING! Thank you for a well made and affordable product!

I ordered these to test the acid and H level of my gardens. I feel these are very accurate in that it gave me different readings for three different plots and to double-check I dipped one if the strips into pure lemon juice. The strip clearly read the high level of acidity in the lemon juice. I am very pleased with the packaging; shows the different levels of pH to compare your strip against. The directions say you need to act quickly once you dip the strip however I found I had plenty of time to compare my strip to the pH scale.I will continue to use these to test the acidity of my soil for plants that require high acid. These are a great option for gardeners.

These seem to work well. My only complaint is that I'm colorblind, and it's impossible for me to accurately read the pH levels (I'm good on the acid colors, but have a hard time with the basic colors, which is where I'm working).

pH strips are not very precise, but if you just need to get a general idea of acidity or alkalinity they are the cheapest and simplest means of measuring liquids. My water stains porcelain blue, which usually indicates acid water and copper pipes being leached of copper. The strip indicates my water is within a point of 6, so it didn't exactly answer my question, but it accomplished all that such strips can. The strips are packaged very well and for a few bucks I now have a several lifetime supply. I wish the measurement had been either 5 or 7 and been definitive, but the strips are what they are. Can be useful for gardener that use Captan fungicide, which becomes ineffective when mixed with alkaline water.

I used this to check the ph of my saliva before and after drinking warm lemon water. It's very interesting to find that after drink lemon water , my saliva is more alkaline. This proved drinking warm lemon water would make your body more alkaline( fighting cancer, ant-inflammation, etc...) The product is easy to use and serve the purpose for what I need, worth the money. I would recommended.

It took nearly 3 weeks for this tiny package to arrive. There are supposed to be 100 individual strips in each package (2). Most of the sheets are clumped together in thick wads that cannot be separated.I managed to pull out a couple of strips to test the water and it appears to work as expected. Not worth the effort to ship them back for a $5 refund.

I got these to test the pH of different lube brands and it worked perfectly. Some the strips were stuck to each other but i just kinda bend them back a forth and they separate so you can rip just one off.

Order just to play around with testing the Ph of different things. They’re Cheap & Work. I think some of the bad reviews are a combination of people not realizing that the ph of whatever they’re testing can be the color of the strip. Also, you can’t completely saturated these or the color will leak out/give you an inaccurate reading.
