    เครื่องโฟโตมิเตอร์-ความกระด้างทั้งหมด (TOTAL HARDNESS Photometer 0-750 mg/L)

    HI 96735

    TOTAL HARDNESS PHOTOMETER

              Total hardness, that is the presence of magnesium and calcium, is due mainly to the runoff water dissolving these salts as it flows or filters through different strata. Hardness can also cause scaling of pipes in cooling and heating systems.

    Order Information:
    HI 96735 is supplied with (2) sample cuvettes with caps, 9V battery and instructions. CAL CHECK™ standards and reagents sold separately.
