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

They are good and work as intended. It is difficult to judge by color, there is a subjective part. But this is normal with color strips pH indicator. They are not a scientific lab grade probe with digital display. They were never intended to be. Keeping that in mind, they work as supposed.

not much to say, they work as advertised. Pro tip: you can get 3 uses out of each strip by tearing the strip into thirds. Also make sure you're dropping a drop into the center of the strip, not dipping it.

These test strips work as described. Thank You

Not an easy product to find, so I was happy to be able to get these strips at a resonable price. The strips are a good weight that does not go limp with moisture. Easy to tear off and in some applications, where only half the lenght is needed, tearing a strip in half still provides eough length to test the liquid without getting my fingers wet. Matching the Ph level has been easy as the colour chart on the container has matched with the colours I have had in tests so far. Not bulky or too small, about the size of a large matchbook.

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.
