High quality dissolved oxygen transmitter meter controller for waste water treatment plant

Product Overview

Description

 

 

Dissolved Oxygen analyzer adopts fluorescence method to measure dissolved oxygen.The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated.

 

Application:   

Wastewater treatment plants:

-O2 control in the aeration basin

-Process water treatment and monitoring

Water works:

-Status monitoring of drinking water (oxygen enrichment, corrosion protection, etc.)

-Water quality monitoring in rivers, lakes or seas

Utilities of all industries:

-O2 control in the biological treatment

-Process water treatment and monitoring

Fish farming:

-O2 control for optimum growth conditions
