    เครื่องโฟโตมิเตอร์-แคลเซียม คาร์บอเนต, แมกนีเซียม คาร์บอเนต (Ca and Mg Hardness Photometer)

    HI 96720


              Water, with exception to distilled water, contains dissolved salts (magnesium and calcium carbonates). The concentration of these salts determines the water Hardness, which can be expressed in calcium carbonate or magnesium carbonate. The sum of these two represents the total hardness level. In addition, this parameter is also related to the phenomenon of pipe rusting in water heating and cooling systems, reverse osmosis and demineralization plants.
