Review on Litmus paper (indicator) for testing water quality 80 pcs, test strips for measuring soil acidity, pH tester 1-14, for water analysis by Ester Hurbanov ᠌

Revainrating 5 out of 5

The best I ever used, recommend it to everybody.

Very approximate, but you can understand what the pH level is. It is necessary to evaluate a couple of seconds after dipping into the test liquid.

Pros
  • No worse than others))
Cons
  • Perhaps someone needs an instruction in 2022, which is missing.
