Antimony pH Electrode by Agra

Determine soil pH quickly and easily.

The Agra Antimony pH Electrode is used in conjunction with a copper sulfate reference electrode to form a pH sensitive cell. The voltage developed between the two electrodes, in contact with the same electrolytem delivers a measurement that when converted is the pH of the electrolyte.

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 wire termination point is a banana jack.

A scale for the conversion of voltage to pH is engraved on the side of the electrode.
