Plastic pH Test Strips, Universal Application (pH 0-14), 100 strips

I used this to check the PH balance of my homemade soap. Tested 3 times because there were no instructions. I wanted to be sure that I got a correct reading. It should have direction telling you how long to leave the strip in the solution. It should at least have a website to inquire about it.

Thank You everything was satisfactory with these strips. Will order them again.

Just what I needed for a QA Lab procedure

strips were defective and returned for credit

Item performs as expected

Great. Wanted to see how this worked against the pH tester.
