PUVCOD-900 Spectrometer UV Type COD BOD TOD Water Probe Sensor OnLine Analyzer
Product Description
Principle of Measurement
Based on the UV absorption reaction by organic matter, the PUVCOD-900 Spectrometer COD 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 values under certain conditions. This method allows continuous monitoring without any reagents.
Main Features
Direct-immersion probe measurement without taking
sampling and pretreatment;
No chemical reagents, no secondary pollution;
Short response time for continuous measurement
The sensor has an automatic cleaning function to reduce maintenance time.
Typical 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.
