Product Introduction

The PFDO-800 dissolved oxygen analyzer uses fluorescence method to measure dissolved oxygen. The top of the sensor is covered with a layer of fluorescent substance. When the blue light emitted by the sensor shines on the fluorescent substance, it is excited to emit red light. Due to the quenching effect of oxygen molecules, the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. The concentration of dissolved oxygen in water can be calculated.

Product Features

The sensor adopts a new type of oxygen sensitive membrane with built-in NTC temperature compensation function, and the measurement results have good repeatability and stability;
There will be no oxygen consumption during measurement, and there are no flow rate/agitation requirements;
Breakthrough fluorescence technology, without membranes or electrolytes, requiring minimal maintenance;
Built in self diagnosis function to ensure accurate data;
Factory calibration, no calibration required for one year, can be calibrated on-site;
Digital sensors with strong anti-interference ability and long transmission distance;
Standard digital signal output, which can be integrated and networked with other devices without a controller;
The on-site installation of sensors is convenient and fast, achieving plug and play functionality.

Typical applications

Online monitoring of dissolved oxygen (DO) in various processes such as regulating tanks, biochemical tanks, and effluent in sewage treatment plants;
DO online monitoring for industries such as waterworks, surface water, water used in various industrial production processes, and aquaculture.
