Online RS485 COD BOD TOC Analyser with Wiper ISO Manufacturer

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 Spectrometer Organic On-Line Analyzer


Measurement Principle

Based on the UV absorption characteristics of organic matter, the PUVCOD-900 Spectrometer Organic On-Line Analyzer utilizes the 254 nm spectral absorption coefficient (SAC254) to accurately measure soluble organic compounds in water. Under specific calibration conditions, the measurement can be reliably converted to COD, BOD, or TOC values. This advanced method enables real-time continuous monitoring without any chemical reagents.


Key Features

  • Direct-immersion probe measurement: No sampling or pretreatment required.

  • Reagent-free operation: Zero secondary pollution, safe and eco-friendly.

  • Fast response & continuous measurement: High efficiency for real-time monitoring.

  • Automatic cleaning function: Self-cleaning sensor design greatly reduces manual maintenance.



  • Continuous organic load monitoring for sewage treatment processes.

  • Real-time influent and effluent water quality monitoring for wastewater treatment plants.

  • On-line monitoring of surface water, industrial effluent, and aquaculture wastewater.
