Test strips & indicator papers
Test strips & indicator papers give a quick semi-quantitative reading by colour change. Laboratories, water treatment sites, schools and production lines use them for pH checks and spot tests where a meter is not practical.
Within the 261 Macherey-Nagel listings are universal indicator papers covering pH 1 to 11 and pH 1 to 14, supplied as reels, reel refill packs and booklets. A reel lets you tear off exactly the length needed, while booklets are convenient for carrying in a pocket or toolbox.
Select the pH range that brackets the values you expect, and choose reel or booklet based on how the paper will be stored and used. Unlike the photometric tube tests elsewhere in the water testing range, these need no instrument at all. Lancetech Limited can quote refill packs in quantity.
