Tinker & Rasor offers a complete line of Copper-Copper Sulfate Reference Electrodes. Made of the most DURABLE PLASTICS, they will withstand severe abuse without damage. The Half Cells have a FULL VIEW WINDOW, that allows liquid level observation without removal of sealed ends.
The pre-saturated ceramic plugs are of a special design for LOWER EARTH RESISTANCE contact and also allow for easy probing in hard earth. These ceramic plugs provide a larger surface area than ever before.
The two standard tips available are the "A" Flat Tip and the "B" Pointed Tip.
Both the Flat and Pointed 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. The "A" Flat tip may be more versatile, as a flat surface can be useful on a variety of electrolytes, such as soils, liquids and concrete.
The "B" Pointed tip has a cone shape which can be easily buried in soils to ensure good contact with the electrolyte.
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 Model 6 reference electrodes.
