    SM21 Single Glass Electrodes
    The glass membrane is the most important part of the complete
    pH measuring loop. pH sensitive glass has the particular property
    that alkali bl ions present in the texture of the glass are
    exchanged with H+ ions of the liquid. The selection of the correct
    type of glass electrode depends on both the type of glass
    membrane thickness of the glass membrane.

    Two types of glass are available, as described here:
    鈥�G鈥� glass
    This is used for the membranes of electrodes in processes where
    the nominal pH value varies between pH0 and pH10. Since
    this type of glass has a wide application range it is also termed
    鈥�general purpose鈥� glass.
    鈥�L鈥� glass
    The application of
    鈥�L鈥� glass is for measurements in alkaline media
    with high process temperatures.

    Thickness of the glass membrane

    Shockproof
    A bulb shaped glass membrane suitable for general purpose
    Heavy duty
    This dome shaped glass membrane is suitable for harsh and
    abbresive applications.
