Corrosion Studies

Measurement of oxygen (in aqueous and gas phases) during corrosion processes can be realized using fiber-optic and contactless oxygen sensors from PyroScience. Typical applications of our optical sensors in such studies are:

  • Determination of dissolved oxygen (DO) consumption
  • Monitoring dissolved oxygen (DO) above corroding surfaces
  • Resolving oxygen gradients developed during corrosion
  • Studies on effects of corrosion inhibitors and other parameters influencing corrosion protection
  • Microbially influenced corrosion (MIC) and impact on degradation of structural steel in marine settings
  • Biocorrosion dynamics in the environment
  • Monitoring of oxygen reduction in closed incubations, respirometric approach

Optical oxygen sensors from PyroScience feature no oxygen consumption, no chemical reaction/alkalinisation during measurements, no electrical interference (compared to polarized amperometric O2 probes), but ultra-fast measurements and high spatial resolution. They are available as retractable micro- and minisensors and without metal parts as bare fiber micro- and minisensors. All oxygen sensors can be read-out with our multi-channel PC-operated FireSting-O2 , multi-analyte meter FireSting-PRO (also in combination with our optical pH sensors), or stand-alone with our pocket oxygen meter FireSting-GO2.


Another advantage of optical sensors compared to electrochemical sensors is the possibility to conduct non-invasive measurements through transparent vessels e.g. for atmospheric corrosion rate monitoring. Contactless read-out from the outside through the vessel wall reduces the risk of leakage.
