Description
VISOCOLOR ECO Nitrite colour chart is a dedicated visual comparison card for nitrite determination in the VISOCOLOR ECO test system used in environmental water analysis. It supports rapid semi-quantitative colour matching so that field and laboratory users can read nitrite results against a standardised colour scale without instrumental photometry. The chart is designed to fit the corresponding VISOCOLOR ECO nitrite test (Art.-Nr. 931044), ensuring consistent colour interpretation between reagent kit and reference scale. Supplied as a single piece with a net weight of 0,01 kg, the compact format is easy to store with portable test kits and routine monitoring sets. Manufactured by Macherey-Nagel, the card belongs to the established VISOCOLOR ECO range for environmental analytics and is intended as a replacement or spare colour reference when the original chart is worn, faded, or missing. Typical use cases include surface water, wastewater, and process-water checks where nitrite is monitored as part of nutrient or discharge control programmes. Clear colour steps help operators compare sample hues under ambient light and document results quickly during sampling campaigns or teaching laboratory work.
This article is part of Colorimetric test kits, in Test kits & water analysis.

Questions about VISO ECO Nitrite Colour card
What is this article?
VISO ECO Nitrite Colour card is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Colorimetric test kits, inside Test kits & water analysis, in Lab chemicals.
A colorimetric kit develops a colour whose intensity tracks concentration. Comparing by eye against a chart and reading a photometer are different versions. The range, the sample volume and the interfering substances named in the leaflet are the specification.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
