Carbonate hardness (temporary hardness) is an important parameter in water chemistry and provides information about the concentration of hydrogen carbonate and carbonate ions in the water. It is part of the total hardness and plays a decisive role in the buffering capacity of the water (pH stability). <\/p>\n
Monitoring carbonate hardness is essential in boiler systems<\/strong>, as carbonate hardness precipitates and forms scale when heated. This impairs heat transfer and can lead to serious damage to the system. The carbonate hardness in boiler water should be as low as possible (< 0.5 \u00b0dH). \n\nIn aquariums, carbonate hardness stabilizes the pH value and prevents dangerous pH fluctuations. A carbonate hardness of 3-10 \u00b0dH is optimal for most fish. Carbonate hardness also plays an important role for water quality in drinking water treatment and pool water. \n\n\n The CALDUR\u00ae Carbonate hardness CH test set works according to the proven acid-base titration method. The hydrogen carbonate is neutralized by adding an acid solution drop by drop to a water sample with Reagent. The color changes at the equivalence point – the number of drops used corresponds directly to the carbonate hardness. <\/p>\n The method is simple, fast and provides reliable results in the measuring range from 0 to 20 \u00b0dH with a resolution of 1.0 \u00b0dH (0.5 \u00b0dH with half the sample quantity).<\/p>\n Ideal for daily checks in boiler systems and aquariums – immediate results<\/p>\n<\/li>\n Covers all practice-relevant ranges, optional 0.5 \u00b0dH resolution possible<\/p>\n<\/li>\n Cost-efficient for regular inspections in waterworks and industrial plants<\/p>\n<\/li>\n No additional devices required – direct reading<\/p>\n<\/li>\n Clearly recognizable end point of the titration<\/p>\n<\/li>\n Choice between hinged lid box and folding box<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Carbonate hardness CH test set – Titration What is carbonate hardness measured for?
