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 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.

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).

we're having fun testing pH in our home!

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.

Work perfectly, very accurate, easy to use & easy to use color chart for results!

Great bang for your buck

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.
