    HI 93745

    Free and Total Chlorine, Total Hardness, Iron and pH Photometer with 555 nm LED

              Chlorine and pH are two of the most closely monitored parameters in water quality tests.

    Hardness is also an important parameter, attentively regulated to reduce waste or ensure proper functioning of equipment. Iron on the other hand can cause an unpleasant taste or stain kitchen ware or laundry.

    With HI 93745 you have a powerful instrument to keep all these parameters under control.

    The microprocessor-based HI 93745 has been factory programmed to read the above parameters with such ease that it can be operated by technical and non-technical personnel alike.

    Order Information:
    HI 93745 is supplied with 3 cuvets, battery and instructions.
