JW-EUV-408(K39) is a multi-parameter water quality analyzer designed for real-time online monitoring of COD, TOC, BOD, TN, TP, NHN, nitrate/nitrite, and turbidity. Using full-spectrum absorption simulation technology, it delivers high-accuracy measurements for industrial wastewater, municipal effluent, and environmental monitoring applications.
2. Product Overview
JW-EUV-408(K39)Multi-Parameter Water Quality Analyzer is designed for continuous online water quality monitoring in wastewater treatment, environmental supervision, industrial discharge control, aquaculture, and surface water applications. Based on simulated full-spectrum absorption technology, the analyzer can measure multiple key water quality indicators without chemical reagents, including COD, BOD, TOC, TP, TN, NHN, nitrate, nitrite, CODMn, color, turbidity, and temperature.
With RS-485 Modbus/RTU output, JW-EUV-408(K39) can be easily connected to data loggers, PLC systems, RTUs, IoT gateways, and water quality monitoring platforms. Its IP68 protection rating, 316L stainless steel housing, and immersion installation design make it suitable for long-term deployment in harsh water environments.
Compared with traditional reagent-based analyzers, this digital water quality analyzer offers easier installation, lower maintenance requirements, faster response, and reduced operating cost. It is a reliable choice for real-time water pollution monitoring, smart water management, and automated environmental monitoring projects.
For project integration, JW-IoT can provide sensor selection support, communication matching, and complete water quality monitoring solutions for industrial, municipal, and environmental applications.
