Dissolved oxygen sensor

Product Description:

The fluorescence-based dissolved oxygen sensor operates by emitting blue light onto a fluorescent layer, which then emits red light. Oxygen concentration is inversely proportional to the fluorescence decay time. This optical measurement method consumes no oxygen during operation, ensuring stable data, reliable performance, and freedom from interferences, while offering simple installation and calibration.
