Product Description

1. Description

JW-MF-520(K40) Online Water Quality Monitoring Buoy is a solar-powered, multi-parameter water quality sensor system designed for real-time, online monitoring of rivers, lakes, reservoirs, and industrial effluents. It supports simultaneous measurement of key parameters including DO, pH, ORP, Conductivity, Turbidity, COD, BOD, TOC, TN, TP, NHN, Chlorophyll, and more, transmitting data via 4G wireless modules to a centralized server. Its robust, IP68-rated stainless-steel housing, easy deployment, and low-maintenance design make it ideal for environmental monitoring, aquaculture, and industrial water management.

2. Product Overview

JW-MF-520(K40) Online Water Quality Monitoring Buoy is a versatile and fully integrated water quality monitoring system. It supports simultaneous measurement of multiple water parameters including Dissolved Oxygen (DO), pH, ORP, Conductivity, Turbidity, COD, BOD, TOC, TN, TP, Ammonia Nitrogen, Chlorophyll, and more. Data is collected directly from sensors and transmitted via 4G wireless modules (or optional NB-IoT) in HEX format to a server, ensuring real-time monitoring. Its buoy-based design integrates chemical analysis instruments, modern sensor technology, solar-powered energy supply, and anchoring systems for robust online monitoring of rivers, lakes, and reservoirs.
