New Optical Dissolved Oxygen Test System offers the latest in dissolved oxygen measurement technology as a complete test capability at an affordable price. This technology is based on the proven method whereas oxygen concentration is determined by the luminescent quenching of a dye embedded on the sensor surface. Unlike polarographic or galvanic sensors, this optical sensor does not require filling solutions, nor a “warm-up” period before use.
A Summary of the Method is:
The sensor has a “lumiphore” or dye material on its surface.
An LED directs blue light to the sensor surface.
The blue light causes a reaction on the lumiphore material. A red light is emitted as the material reacts.
The time for the red light emission is measured by the optical sensor.
A red LED is used as a reference for comparison.
The more oxygen present in the sample causes a decrease in the red light emission time. This red light emission time is measured by the optical sensor and correlated to the oxygen concentration.
