Antimony Electrode

AGRA Antimony Electrode

The Antimony Electrode is used in conjunction with a copper sulfate electrode to form a pH-sensitive cell, determining soil pH quickly and easily. The voltage developed between the two electrodes in contact with the same electrolyte delivers a measurement that when converted is the pH of the electrolyte. The range is approximately 1 to 11. The unit is eight inches long and contains an antimony slug 5/8" in diameter. There are no liquids. The terminal is a binding post. A scale for the conversion of voltage to pH is engraved on the side.
