The online dissolved oxygen analyzer is a detection device suitable for industrial wastewater, aquaculture, river monitoring, swimming venues and other fields. It is equipped with fast colorimetric detection reagents and can measure quickly, simply, accurately and stably. It has a beautiful appearance, simple operation interface, accurate detection system, and helps users obtain fine data. It can analyze water conditions more accurately and effectively, prevent breeding risks in advance, and avoid losses in a timely manner.

Working principle of online dissolved oxygen analyzer:

The oxygen content in water can fully demonstrate the degree of self purification of water. For biological treatment plants using activated sludge, it is crucial to understand the oxygen content in the aeration tank. An increase in dissolved oxygen in wastewater can promote biological activities other than anaerobic microorganisms, thereby removing volatile substances and easily oxidizable ions, and purifying the wastewater.

There are three main methods for measuring oxygen content: automatic colorimetric analysis and chemical analysis measurement, paramagnetic method measurement, electrochemical method measurement, and fluorescence method. The dissolved oxygen in water is generally measured by electrochemical method.
