Owl - Test Station Brochure

With more data, the Owl is the wisest of all test stations. To understand what makes the BSI Owl Test Station so unique, it is helpful to briefly take a look at the purpose of test stations and cathodic protection in general. The concept of Cathodic Protection (CP) is not new. It is a technique that is used to control the corrosion/erosion of a metal surface by making the metal surface the cathode of a dissimilar “sacrificial” metal, also known as the anode. Electrons from the different types of metal travel from anode to cathode and, in the process, combine with oxygen and water. Different combinations of the electrons, water, oxygen and the steel cathode cause corrosion/erosion.
