There was a need to find in today's variety of goods and services such a thing as pH test strips. Daily monitoring of the pH of the child's urine was necessary. After a short search, the choice fell on pH Special test Paper litmus strips, found by the way in our city in just one place (this fact is interesting because these tests seemed to me very optimal from all sides, and this is definitely a profitable indicator for commercial activity, but nevertheless ...). So, what influenced the choice and the final result. The range and accuracy of pH value gradation (pay attention to the range of pH values - it is the same as it lies in the limit of change in the pH of human urine), the convenience of displaying the visual result on the strip, the unambiguous interpretation of the result (for this, I advise you to look at the strip always under the same lighting ), the number of test strips - 100 pcs., packaging-container, expiration date and of course the price.
