Total Hardness Liquid Reagents – Kit to Measure (50 Tests)

Total Hardness Liquid Reagents – Kit to Measure (50 Tests) are photometer-compatible replacement / refill consumable liquid reagents used for accurate pool & spa testing. Key Specs Product type: Replacement / refill reagent (consumable) Test parameter: Total hardness Range: 0.0 - 500.0 mg/l (ppm) Format: Liquid reagent kit (50 tests) Shelf life: 6 months (from the date you receive it) What this reagent does 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
