In waterworks, manganese must be reliably removed, as even low concentrations can lead to operational disruptions. <\/p>\n<p>Manganese can cause deposits and corrosion in cooling water systems and industrial treatment.

After adding three reagents to the water sample, a colored complex is formed within 10 minutes, the intensity of which is proportional to the manganese concentration. <\/p>\n<p>The measured value is determined by direct color comparison with a supplied color chart.<\/p>\n<h3>Advantages of the CALDUR\u00ae test set<\/h3>\n<ul class=\"feature-list\">\n<li>Sensitive measuring range 0.03 &#8211; 1.0 mg\/l Mn\n<p style=\"text-indent: 30px; font-style: italic;\">Already detects concentrations below the drinking water limit value<\/p>\n<\/li>\n<li>100 provisions per set\n<p style=\"text-indent: 30px; font-style: italic;\">Economical for regular checks<\/p>\n<\/li>\n<li>Proven formaldoxime method\n<p style=\"text-indent: 30px; font-style: italic;\">Selective for manganese, low interference<\/p>\n<\/li>\n<li>Easy handling with color card\n<p style=\"text-indent: 30px; font-style: italic;\">Fast on-site determination without measuring devices<\/p>\n<\/li>\n<li>Robust plastic housing with hinged lid\n<p style=\"text-indent: 30px; font-style: italic;\">Safe transportation and protection of reagents<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>CALDUR\u00ae Manganese Test Set &#8211; Colorimetric What is manganese measured for?
