Abstract
Condensed moisture in devices and/or pipe conduits for anti-corrosion applications in chemical engineering is measured at least one point in the devices and/or pipe conduits by measuring an electrochemical potential difference across two different elements, such as iron and copper, which are arranged one beside the other spaced from 0.001 to 1 mm from each other by an electrically insulating material so as to be electrically insulated from each other. An apparatus for making these measurements is also described.
