Nitrite (NO\u2082-) is formed as an intermediate product during the bacterial oxidation of ammonium to nitrate (nitrification). It is an important Reagent for water quality, as its presence indicates incomplete biological treatment or fresh contamination. The limit value for drinking water is 0.5 mg\/l NO\u2082-<\/strong> (Drinking Water Ordinance). <\/p>\n Nitrite is harmful to health as it can affect the oxygen supply in the blood (methaemoglobinaemia). A low nitrite concentration is particularly important for infants. <\/p>\n Nitrite is one of the most critical parameters in aquaristics, as even low concentrations are toxic to fish. In fish farming recirculation systems, seamless monitoring is essential. <\/p>\n The CALDUR\u00ae Nitrite LR Test Set – Colorimetric is based on the NED method (N-(1-naphthyl)-ethylenediamine). After adding a reagent to the water sample, a pink to violet coloration develops within 5 minutes, the intensity of which is proportional to the nitrite concentration. <\/p>\n The measured value is determined by direct color comparison with a supplied color chart.<\/p>\n Detects concentrations well below the drinking water limit value<\/p>\n<\/li>\n Particularly economical for regular checks<\/p>\n<\/li>\n Results directly on site<\/p>\n<\/li>\n Particularly easy handling<\/p>\n<\/li>\n Safe transportation and protection of reagents<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Nitrite LR Test Set – Colorimetric What is nitrite measured for?
