Optical Oxygen and pH Sensors
Feb 2012Ocean Optics Inc.Request Info
For monitoring of food and fermentation processes, Ocean Optics Inc. has produced optical oxygen and pH sensors. The fiber optic sensors are designed for accurate in situ measurements in various media. Proprietary sensor coating materials do not consume the sample and can be applied to substrates such as probes, self-adhesive acrylic patches and microtiter wells. Coating options are available for general lab use, food processing lines and hydrocarbon-rich environments. Depending upon the application, oxygen presence or pH can be visually determined by color change with a handheld LED, or a fluorometer can be used to make exact measurements. The company says that its optical oxygen and pH patches overcome the limitations of electrochemical-based oxygen and pH sensing. They can be integrated within a small-scale biosystem.
