Ph Test Strips, 160 Full Range Strips 1-14 Universal Litmus Paper Soap Making For Water Saliva Wine Urine Soil, 2 Packs Of And 6 Units

Really nice product. Strips tear out easily and very easy to read. I had three different water sources I wanted to check and you can see by the pic, the differences (which I completely expected) showed very clearly (would be easier to see if I put it on a white background for u to see) Only suggestion is to have the comparative color guide on the outside of the cover and not inside. I don't want to contaminate the unused strips accidently even though there is a minor chance of it happening. The white page directly beneath the strips (which covers the unused strips) is also nice, but would be better on the side to more easily compare with the color chart, but overall a great product.

I use these with my cat that is prone to urinary tract infections. Really helps me stay on top of her health.

Convenient little folder of Litmus strips for pH testing, color chart included.

Do what they should .work perfect

These seem to work when you need a pH measurement in a pinch. I wouldn't use these for accuracy, but are easy to use and the colors change according to pH chart.
