    ชุดทดสอบแคลเซียมในน้ำ (0 -125 ppm.,0 -250 ppm.)

    HI 38086

    Calcium (Ca) – Range (0-125 mg/L) (0-250 mg/L)

    Hardness in water is mainly due to the presence of Calcium and Magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in order to prevent scaling and corrosion.

    Water is categorized as very soft (0-70 mg/L), soft (70-150 mg/L), slightly hard (150-250 mg/L), moderately hard (250-320 mg/L), hard (320-420 mg/L) and very hard (420 mg/L and above), according to the hardness scale. HANNA®‘ kits cover all of these ranges.

    HANNA® offers the HI 3840-S, HI 3841-S and HI 3842-S chemical test kits packed in sachets offering a low cost alternative.
