AirCorr: Corrosion

Real-time monitoring of indoor and outdoor corrosivity and air quality.

AirCorr measures and registers the change over time in the electrical resistance (R) of a thin metal track applied on an insulating substrate. If the metal corrodes, the cross-sectional area of the track decreases and the ER increases. The changes in R can be directly translated into corrosion depth and corrosion rate.

Features and benefits

  • AirCorr measures and registers the change over time in the electrical resistance (ER) of a thin metal track applied on an insulating substrate. If the metal corrodes, the cross-sectional area of the track decreases and the ER increased. The changes in ER can be directly translated into corrosion depth and corrosion rate.
    The AirCorr monitoring system is comprised of an electronic logger for measuring and recording ER, a metal sensor that actually corrodes in the environment, a non-contact communication interface between the logger and computer, and a suer-friendly software programme.
  • Examples of use

  • Real-time monitoring of indoor and outdoor corrosivity and air quality
  • Control of the air in museums, exhibitions, depositories, archives.
  • Design of better measures for corrosion protection of vehicles and transported goods.
  • Protection of electronic equipment in clean rooms, GSM stations, pulp & paper industry, cars, and ships.
  • Development of corrosion tests, understanding of corrosion mechanisms.
  • Sensors

  • Both thin-film sensors with extreme sensitivity for indoor use and robust thick-film sensors for corrosive environments can be purchased.
