Ocean Optics optical O2 and pH sensors provide real-time, in situ measurements in various media. The sensor coating materials do not consume samples and can be applied to substrates such as probes, self-adhesive acrylic patches and microtiter wells; coating options are available for food processing lines. Oxygen presence or pH can be visually determined by color change with a handheld LED.
