VISOCOLOR® ECO Test Ammonium 3

A standalone test kit for the chemical analysis of water samples that needs no additional apparatus or prior chemistry knowledge. The colour templates on the VISOCOLOR® card are matched to the colours of freshly prepared standard solutions, giving fine resolution, precision and reproducible results. Ammonium is determined as a blue indophenol dye over a measuring range of 0.2–3 mg/l NH₄⁺, with enough reagents for 50 tests. The kit includes reagents, measuring glasses, a slide comparator, a colour chart, a syringe and instructions in six languages.
