    Reference Electrode, Mercury/Mercury Sulfate, Double Junction

    Part Number
    RREF0026
    Product Discontinued – No Replacement
    This product has been discontinued and can no longer be purchased. There is no replacement available at this time. The product remains on our website for reference and a listing of its specifications.

    Pine Research suggests purchasing and using standard double junction Ag/AgCl reference electrode instead..

    The standard-sized, double junction, mercury/mercury sulfate (Hg2SO4) reference electrode is filled with saturated K2SO4 solution. The refrerence electrode body is 9.5 mm OD, therefore ideally used with Standard volume electrochemical cells. The reference electrode is designed to be pass through a 14/20 ground glass joint and held in place by the included PTFE adapter, which can be adjusted to control the immersion depth of the reference electrode into the cell. Pine Research recommends proper storage and use of reference electrodes. A variety of useful tools for storage and care are shown below.
