TECHNICAL FEATURES
The Cathodic protection is a technique to control the corrosion of a metal surface by making it work as a cathode of an electrochemical cell. This is achieved by placing in contact with the metal to be protected another more easily corroded metal to act as the anode of the electrochemical cell.
Cathodic protection systems are most commonly used to protect steel, water or fuel pipelines and storage tanks, steel pier piles, ships, offshore oil platforms and onshore oil well casings.
The bench is provided with measuring facilities characterized by suitable sensitivity and accuracy, in order to introduce which must be the basis of the laboratory tests to be executed, to recognize whichis the correct way in order to determine the behavior of a metal in contact with the electrolyte in different conditions of temperature (thermostatic bath) and in high oxygen concentration (air insufflations pump).
A suitable multi-channel interface can connect the bench to a PC in order to record the experiment results and give the trace for further studies.

Cathodic protection training bench.
NOTE:
The DL MK2 version of the Cathodic Protection trainer differs from the DL MK1 version on the possibility of performing simultaneously the same experiment with different values of the parameters. In the DL MK2 version, the experiments can be performed in sequential mode, that is, if you want to change the value of a specific parameter, you can do it after performing the same experiment with the previous value. You must then record the results on your notebook and then compare the different results. With the DL MK1 version you can perform the same experiment with two different parameter configurations at the same time.
