The Experimental Set-up consists of a metal container with a built in heater, a pressure guage and a carbon dioxide supply (to dissolve calcite).
The heater is connected to a temperature stabilizer (to control the temperature inside the container). A pipe from the container leads to a cell which is wound by a solenoid. The solenoid is connected to a voltage controller. In the cell, a coupon (stainless steel) is placed  on which the scale will be formed.

The metallic container wil contain a saturated calcite solution. As the solution will pass through the cell, the pressure will drop and a certain amount of calcite will precipitate  and form scale on the coupon. The coupon will then be taken out of the cell and studied under a microscope, and the amount of scale formed on it will be determined by weighing.
