Cathodic protection testers inspect cathodic protection systems of buried or submerged metal piping and tank systems. Cathodic protection is the utilization of the electrical properties of corrosion of metallic substances to provide a system for the protection of steel underground storage tanks, metallic piping or any other buried metallic structure, to extend their useful life (to prevent underground storage tanks from rusting).
Sixteen states require cathodic protection testers to obtain licenses. All require about eight days of coursework; Iowa and New Jersey also
require two years of experience. Nearly every state requires workers to pass two exams; Alaska requires only one.
