PUVCOD-600 UVCOD Online COD TOC BOD Turbidity Analyzer


Measurement Principle

The PUVCOD-600 UVCOD online water quality sensor is based on the UV absorption principle of organic substances in water.
It utilizes 254nm spectral absorption coefficient (SAC254) to accurately detect the content of soluble organic compounds in water.
Under professional algorithm conversion, it can stably output COD, TOC, BOD and other organic parameters, and realize real-time online monitoring of water organic load.

The whole detection process requires no chemical reagents, achieving pollution-free and long-term continuous monitoring.


Core Features

  • Adopt 254nm UV spectral detection technology, realize multi-parameter simultaneous measurement of COD, TOC, BOD and turbidity

  • Direct immersion probe design, no need for sampling and water sample pretreatment

  • Reagent-free detection, no secondary environmental pollution, low operation cost

  • High-efficiency LED light source, compact structure, low power consumption, easy on-site integration and installation

  • Built-in automatic cleaning device, effectively reduce dirt accumulation and manual maintenance

  • Equipped with power positive and negative reverse protection and RS485 terminal protection, strong anti-interference ability

  • Support real-time time display, data storage and historical data query

  • Flexible configuration, optional wireless data transmission module for remote monitoring-


Application Scope

  • Online monitoring of organic pollutants in sewage treatment plants, real-time detection of inlet and outlet water quality

  • Continuous monitoring of industrial wastewater production and discharge water quality

  • Surface water, river water, lake water and environmental water quality monitoring

  • Fishery water, circulating water and other water body organic component detection
