Fiber Optic Oxygen Sensors are phase fluorometer-coupled chemical sensors for full spectral analysis of dissolved and gaseous oxygen pressure. A fluorescence method is used to measure the partial pressure of dissolved or gaseous oxygen.

A Fiber Optic Oxygen Sensor system will change the way you work. Because the probe consumes no oxygen, it can be used in continuous contact with viscous samples so that continuous stirring is no longer required. Now that there is an alternative to the oxygen electrode, changing membranes and filling solutions can be avoided.

Oxygen Sensor System – Sample Setup

Optical fiber carries excitation light produced by the blue LED to the thin-film coating at the probe tip. Fluorescence generated at the tip is collected by the probe and carried by the optical fiber to the phase fluorometer. When oxygen in the gas or liquid sample diffuses into the thin-film coating, it quenches the fluorescence. The degree of quenching correlates to the level of oxygen pressure.
