Optical Online Dissolved Oxygen Analyzer For Industrial Application
Dissolved oxygen refers to molecular oxygen dissolved in water. It is an indispensable condition for the survival of aquatic organisms and an important indicator of the degree of organic pollution in water bodies.
The rapid, accurate and continuous measurement of dissolved oxygen content in water bodies is of great significance to the development of industrial and agricultural production, environmental monitoring, and aquaculture.
The set of Daruifuno dissolved oxygen analyzer is reliable, flexible and low-maintenance. The dissolved oxygen meter and sensor are designed for the application of industrial online environment.
The dissolved oxygen controller is digital and has automatic compensation for air pressure display. The matched DO sensor adopts Fluorescence principle.
