Colorimetric water test kits
Colorimetric water test kits give a visual colour-change reading for pH and dissolved parameters without a photometer. Water treatment plants, aquaculture sites, environmental laboratories and teaching labs use them for rapid on-site checks and routine water analysis.
This section holds 957 Macherey-Nagel listings, including universal indicator paper in pH 1–11 and pH 1–14 ranges, supplied as reels, refill packs and booklets. A colour chart on the pack turns each reading into a value, so no instrument or calibration is needed, which makes these kits practical for field sampling as well as the bench.
When choosing a colorimetric test kit, match the measuring range to the sample and consider whether a reel or booklet format suits your workflow better. For a specific parameter or pack size, ask Lancetech Limited for a quotation.
