Online COD, Ammonia Nitrogen, Total Phosphorus, and Total Nitrogen Analyzer, COD to 3000 mg/L (CAT#: STEM-AL-4030-ZJF)

Online COD, Ammonia Nitrogen, Total Phosphorus, and Total Nitrogen Analyzer is designed for continuous online analysis of COD, ammonia nitrogen, total phosphorus, and total nitrogen. A dedicated sensing or colorimetric method converts the sample response into a quantitative result. The sample path or flow cell presents water to the measurement element. Electronic control manages measurement timing, compensation, and output functions. The display provides current readings and operating status. Alarm and communication outputs support integration with process-control systems. Calibration and maintenance procedures preserve measurement performance over extended operation. The enclosure supports fixed installation in the documented operating environment. The analyzer supports repeatable continuous measurement within the stated range.
