A potentiostat\/galvanostat controls the electric potential by modulating the current between the pipe and a surface counter electrode. The principle interpretive tool used in this study was an Artificial Neural Network (ANN) that had been \\trained\\\" on simulated pipe with a defective coating and on field data from a test pipe.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44361937223758,"sku":"18451","price":350.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51750-new-technique-to-assess-level-of-cathodic-protection-in-underground-pipe-systems-phases-i-and-ii","provider":"PRCI Store","version":"1.0","type":"link"}
