Portable Copper-Copper / Sulfate Reference Electrodes

Article No. 10907

8-A Copper Sulfate Electrode

The Tinker & Rasor Copper-Copper/Sulfate (CSE) Half Cell Reference Electrodes have multiple electrodes available so depending on your applications there is one to suit your needs. They are designed for pipe to soil potentials, close interval surveys, structure to cell, and lab use, and can withstand harsh environments.

  • Long lasting tips
  • Strong body for outdoor use
  • High purity copper and coppersulfate
  • Rechargeable allowing you to maintain accuracy for a longer time
  • Optional Clear View tube
  • Temperature sensor
  • For use with most CP Voltmeters
  • Tip grooves increase the surface area of the tips
  • The knurled nut on a 1/4" rod allows for an easier lead connection (1/4" rod not available for 2-A models)
  • There are 2 different tip styles to choose from you have the option to select which one will work best for you.
    • The “A” tip is a flat tip allowing you to easily test on most electrolytes like soils, liquids, and concrete.
    • The “B” tip is a cone shaped tip allowing it to easily be buried in soils to maintain a good contact with the electrolyte.
  • Both the Flat (A) and Pointed (B) tips are made to maximize the total surface area of the tip to ensure good contact area with the electrolyte. Mainly a user preference, there is no performance difference between the two types of tip. While the body of the half cell is printed with the tip type, all parts are interchangeable and an "A" or "B" tip can be put on any of the Models 6 and 8 reference electrodes.
  • There are 6 different electrode body styles to choose from:
    • 2-A “Pencil Cell”: This small electrode is nicknamed the “Pencil Cell” due to the fact that it holds very similar dimensions to a pen or pencil. This makes it easy to carry around because it takes up barely any room. There is also an optional extension handle offered for this electrode.
    • 3-A “Fat Boy”: This electrode nicknamed the “Fat Boy” is designed specifically for use on concrete surfaces. It has a 3" diameter with a waffle pattern tip allowing for an increase in surface area over the electrolyte. To allow for an even better contact to the concrete a sponge is conveniently included and carried in the cap of the electrode allowing you to place it between the half cell and concrete.
    • 6-A and 6-B: These electrodes are around 6" in length and perfect for use in the field.
    • 8-A and 8-B: These electrodes are around 8" in length.  These half cells contain more copper rod, copper sulfate crystals, and more water thanks to the larger size of the tube.
