2-A Pencil Cell
3-A For Concrete
6-A, 8-A Flat Tips
6-B, 8-B Pointed Tips
Tinker & Rasor offers a complete line of Copper-Copper Sulfate Half Cell Reference Electrodes. All Tinker & Rasor HALF CELLS are made from the most durable materials available, to withstand years of harsh, even severe field use! These fully "serviceable" Half Cells can be recharged to assure accurate readings for many years. Replacement "Tips" and supplies are available from stock.
"A" tip vs. "B" tip
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 Models 6 and 8 reference electrodes.
Model 6 vs. Model 8
Tinker & Rasor offers the Model 6-A, 6-B and the Model 8-A and 8-B. The difference is in the length of the half cell only. The overall length of the 6 Model is 6" and the 8 Model is 8"
The Model 8 half cells contain more copper rod, more copper sulfate crystals and more water due to the larger volume of the tube.
Model 3-A "Fat Boy"
|The Model 3-A Fat Boy reference electrode has been designed specifically for use on concrete. The large surface area, 3" diameter, has a waffle pattern like the "A" tips of the Models 6 and 8, again to increase surface area of the tip. To ensure good contact of that surface area to the rough and porous surface of concrete, a wet sponge is placed between the half cell and concrete. The sponge is include with the Model 3-A, and is stored in the Black vinyl tip cover.|
Model 2-A "Pencil Cell"
|The 2-A "Pencil Cell" includes high purity copper-sulfate, a strong body for outdoor use and long lasting tips. The 2-A also has a optional extension handle available.||
