The design and operation of a new atmospheric corrosion rate monitor (ACRM) is described. The ACRM is operated and the data are stored on magnetic tape by a data logging system (ACRMDL) which can be battery operated. Data obtained with the ACRMDL are transferred to a larger computer for display and analysis. The use of zinc and nickel ACRMs on test sites in Southern California is illustrated with plots of the inverse polarization resistance, relative humidity (RH), and temperature as a function of exposure time for ACRMs facing skyward and downward. Examples for the results obtained in a laboratory study are illustrated for exposure of zinc and nickel ACRMs to air containing 1 ppm SO2 over a 28-day period.
