n Principle of Measurement
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.
n Main Features
u Direct-immersion probe measurement without taking sampling and pretreatment;
u No chemical reagents, no secondary pollution;
u Short response time for continuous measurement
u The sensor has an automatic cleaning function to reduce maintenance time.
n Typical Application
u Continuous monitoring of organic load during sewage treatment, online real-time monitoring of influent and effluent water quality of wastewater treatment plants;
u Continuous on-line monitoring of surface water, industrial effluent, and fishery wastewater.
