(POL2010TH12)  Hardness | 0.0 - 500.0 mg/l (ppm) | reagent for measurements - Total hardness. The shelf life of liquid reagents is 6 months.Keep containers tightly closed in a dry, cool and well-ventilated place. Protect frommoisture. Store locked up. Keep out of the reach of children. Store away fromother materials.Basically dissolved salts belonging to the alkaline earth elements calcium and magnesium are found in non-distilled water. In rare cases, strontium and barium can also be found. These combine with carbonate ions to form water- insoluble compounds (calcium). Through the total hardness measurement, the potential danger of calcium precipitation is measured as the required carbonate ions form from hydrogen carbonate ions when water heats up or when there are pH values that are greater than 8.2 (comp. Alkalinity). When measuring calcium hardness (SVZ1300 tablet process), only the part of the dissolved calcium in water is measured. The amount of magnesium dissolved in water is de
