Introduction:

Dissolved oxygen is the most important parameter in the biochemical process of aquatic environment. It is also often used as a tracer in marine research. The optical dissolved oxygen sensor is a high-performance, low-power in-situ sensor for measuring the dissolved oxygen. It has so many advantages: small size, low power consumption, fast response,high stability, etc. It can provide long-term stable, accurate and reliable dissolved oxygen measurement data, which can be widely used in marine environmental investigation and monitoring.

Principle

Based fluorescence quenching measurement principle. It is equipped with a light isolating coating to protect the internal fluorescent materials from sunlight and other light. One side of the fluorescent film is exposed to the ambient water, and the other side is installed on the optical window of the measurement room. The blue material excites the fluorescent material on the fluorescent film to make it emit red light, the detector detects the signal that releases the red light, and then obtains the dissolved oxygen concentration after temperature compensation.

Applications

l  Shallow water areas with algal blooms

l  Aquaculture

l  Fjords or areas with little water exchange
