40 key water and wastewater quality parameters with 73 different methods covering multiple ranges are programmed into the meter. Wastewater treatment digestion parameters include COD, Total Nitrogen and Total Phosphorous, which are important for monitoring nutrient removal. The HI-83399 also offers an absorbance measurement mode for performance verification and for users who would like to develop their own concentration versus absorbance curves.
The Chemical Oxygen Demand (COD) parameter is included for industrial and municipal wastewater treatment. The Phosphorous and Nitrogen parameters included are beneficial to municipal wastewater treatment customers that need to monitor their biological and chemical nutrient removal process. This photometer features an innovative optical system that uses LEDS, narrow band interference filters.
