A review-(1) and current status description is provided for the corrosion coulometer. The device was developed for monitoring corrosion on unpainted weathering steel structures and to provide an assessment of steel corrosivity in the local environment. The technology has been field tested in eight states and diverse environments. Developments of the coulometer have focused on providing inexpensive and convenient implementation, as well as, tailoring the sensor to address specific needs. Design modifications have been made to the sensor to address specific application needs and an inexpensive data logging device has been developed to provide for ease of use and acquisition of detailed corrosion data.
