Which substances can interfere with the optical O2, pH and CO2 measurements?

  • High concentration of fluorescent substances can interfere. Please contact us for solutions solving this issue.
  • Our sensors are made for aqueous solutions. Higher concentrations of organic solvents should be avoided. Optical oxygen sensors do even stand pure ethanol.
  • pH and CO2 sensors show cross sensitivity for ionic strength (osmolarity). This can be compensated by a one point re-calibration.
