Copper (Cu) is an essential trace element, but can be harmful to health in high concentrations. The limit value for drinking water is 2 mg\/l<\/strong> (Drinking Water Ordinance). Copper mainly enters drinking water through copper pipes, especially in soft, acidic water with a low pH value. <\/p>\n Elevated copper concentrations can lead to a greenish discoloration of the water, cause a metallic taste and trigger gastrointestinal complaints in sensitive people. In aquariums, even small amounts of copper are toxic to fish and invertebrates. <\/p>\n Regular monitoring of the copper content is therefore particularly important for new copper installations, in aquariums, swimming pools and in industrial water treatment.<\/p>\n The CALDUR\u00ae Copper Test Set – Colorimetric works according to the cuprizone method. Cuprizone forms a blue to violet color complex with copper(II) ions, the intensity of which is proportional to the copper concentration. <\/p>\n After the addition of two reagents and a reaction time of 5 minutes, the measured value is determined by direct color comparison with a 6-stage color chart.<\/p>\n Covers the entire relevant range up to the drinking water limit value<\/p>\n<\/li>\n Economical for regular checks<\/p>\n<\/li>\n Fast on-site determination without measuring devices<\/p>\n<\/li>\n Proven, reliable detection method<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Copper Test Set – Colorimetric What is copper measured for?
