UNI20+PUVCOD-600 Spectrometer Organic UVCOD BOD Turbidity Water OnLine Sensor Analyzer

COD and BOD can be indicated as mg/L or ppm (parts per million).
Both parameters measure the amount of oxygen needed to oxidize pollutants in water.
Also, both measurements indicate the intensity of water pollution.
Almost all wastewater treatment plants are required to measure one of these three items as a measure of the pollution value in the water. COD should always measure higher than TOC and then BOD.

Measurement Principle



Based on the UV absorption reaction by organic matter, the PUVCOD-

600 Spectromete Organic On-Line Analyzer uses the 254 nm spectral

absorption coefficient SAC254 to measure the content of soluble

organic compound in the water, and it can be converted to COD or

BOD values under certain conditions. This method allows continuous

monitoring without any reagents.


Features

 Direct-immersion probe measurement without taking sampling and

pretreatment;

 No chemical reagents, no secondary pollution;

 Short response time for continuous measurement

 LED light source, small size, low power consumption, easy to integrate on-site

 The sensor has an automatic cleaning function to reduce maintenance time.

 Sensor power supply positive and negative reverse connection protection

 Sensor RS485 A/B terminal is connected to the power supply protection

 With time display, data storage and historical data viewing function;

 Optional data wireless transmission module.



Application

Continuous monitoring of organic load during sewage treatment, online real-time monitoring of influent and effluent water quality of wastewater treatment plants.

Continuous on-line monitoring of surface water, industrial effluent, and fishery wastewater.
