A system for watching corrosion of a metal tube for a gas scrubber is provided to check whether the metal tube is corroded or not by measuring a resistance value between an outer surface of the metal tube and a metal electrode formed inside of the metal tube. A system for watching corrosion of a metal tube(10) for a gas scrubber includes an electrode pattern sheet(20), a Parylene coating film(30), a resistance measuring unit(40), and a control unit(50). The electrode pattern sheet is installed inside of the metal tube. The Parylene coating film is coated on a surface of the electrode pattern sheet. The resistance measuring unit measures a resistance between an outer surface of the metal tube and a metal electrode formed on the electrode pattern sheet. Resistance values measured from the resistance measuring unit are inputted into the control unit to put the resistance values into a database.
