Water analyzer BH-485-COD

wastewaterunderground watermonitoring

Based on the absorption of ultraviolet light by organic matter, spectroscopic organic material online sensor adopts the 254 nm spectral absorption coefficient SAC254 which is used to reflect the important measurement parameters of the soluble organic matter content in water, and it can be converted into COD value under certain conditions. This method allows for continuous monitoring without the need for any reagents. •Calibration-free •Extremely robust •Minimal cleaning effort •Digital RS485 output • Directly connect to PLC or computer Optimal for the measurement of TOC and DOC in the inlet/effluent of municipal wastewater treatment plants.
