PUVCOD-900 Online RS485 Probest COD BOD TOC water quality testing equipment for industrial sewage water

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.

PUVCOD-900 China Probest High Quality Wholesale COD BOD TOC water quality testing equipment for industrial sewage water


Measurement Principle



Based on the UV absorption reaction by organic matter, the PUVCOD-900 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.


² Direct-immersion probe measurement without taking sampling and pretreatment.

² No chemical reagents, no secondary pollution.

² Short response time for continuous measurement.

The sensor has an automatic cleaning function to reduce maintena
