Product Description

1. Description

JW-MPS-400(K32) multiparameter water quality sensor is designed for continuous online monitoring of up to 8 water quality parameters including temperature, dissolved oxygen, COD, pH, ORP, conductivity, salinity, ammonium, and turbidity. With RS485 Modbus RTU communication, automatic self cleaning, IP68 waterproof protection, and submersible installation, it is ideal for long term water quality monitoring in rivers, reservoirs, wastewater treatment, aquaculture, industrial water systems, and environmental monitoring stations.

2. Product Overview

JW-MPS-400(K32) multiparameter water quality sensor is an integrated online monitoring probe designed to measure multiple water quality indicators in one device. It can be configured with different digital sensor modules according to project requirements, including dissolved oxygen, COD, pH, ORP, conductivity, salinity, ammonium, turbidity, and temperature.

The built in automatic cleaning device can clean the sensor surface at preset intervals and cleaning cycles. This helps reduce microbial attachment, improve measurement stability, and lower maintenance costs in long term water monitoring applications. The protective front guard prevents large suspended solids and aquatic organisms from damaging the sensor probes while maintaining measurement accuracy.

With RS485 Modbus RTU output, the sensor can transmit data directly to data acquisition units, PLCs, RTUs, SCADA systems, wireless gateways, and cloud based IoT platforms. Its submersible installation design and IP68 protection make it suitable for rivers, lakes, reservoirs, aquaculture ponds, wastewater plants, and industrial process water monitoring.When combined with a data logger, communication gateway, power supply, cloud platform, and alarm module, this multiparameter probe can serve as the core sensing unit of a complete water quality monitoring system.

4. Installation and Maintenance Notes

During installation, the sensor should be fixed using a lifting ring or pipe thread mounting method. Avoid direct force on the cable to prevent cable damage. For long term operation in water, seawater, wastewater, or humid outdoor environments, all wiring joints should be waterproofed, and user side cables should have corrosion resistant protection.

The sensor includes a cleaning brush to extend the maintenance interval, but regular inspection is still recommended. Check whether the sensor head has dirt or microbial attachment, whether the housing and sensor surface are damaged, whether the cable is normal, and whether measurement data is stable. Clean the sensor surface with tap water, and gently wipe with a wet soft cloth if debris remains.

JW-IoT can integrate this sensor with 4G, LoRaWAN, RS485, RTU, SCADA, and cloud platforms to build a multi-parameter water quality monitoring solution for remote field deployment.
