Oxygen and pH Sensors

Our optical sensors use light to probe the interaction between a sample and one of our proprietary sensing materials in order to quantify a chemical property of the sample. Our oxygen and pH sensors have been used to monitor biological samples, headspace gases, and industrial slurries, cosmetics, foods, and liquids in natural environments.

Advantages of Optical Chemical Sensors

  • Easily applied to probes, patches, cuvettes, and other media
  • More robust and require less maintenance than most electrodes
  • Do not consume or alter the chemical composition of the sample
  • Less susceptible to environmental changes, moisture, and interfering chemicals
