Ahlstrom offers a range of test papers for rapid determination of pH and other conditions. Universal pH indicator papers are available in a roll of 5m in a plastic case, a refill pack of 3 reels for that case, and in a box of 200 strips. pH test strips, which have small squares of paper, each prepared with a different indicator, are also available.
Ahlstrom pH test strips are used for rapid determination of pH with improved handling over pH papers because the colored bands are bonded to a thin and flexible plastic strip.They are often able to provide a more precise measurement than a single paper alone.
Ahlstrom pH papers are used for rapid determination of pH value. The roll format is convenient for using as much or as little indicator paper as needed.
