I use pH test strips when I tan pelts. I used to have test strips that only covered about 3 levels. I like the range of these strips and the fact that you can choose the size. Having strips on a roll is easier and I don't spill strips and contaminate everything. Great product at a reasonable price. I will buy these again.
