Multi Parameter Probes – Description

A Multi-Parameter Probe (MPP) is an integrated sensor system designed to measure multiple water quality parameters simultaneously using a single probe. It is widely used in rivers, lakes, reservoirs, wastewater treatment plants, groundwater monitoring, aquaculture, and industrial water applications.

Typical Parameters Measured

• pH
• ORP (Oxidation Reduction Potential)
• Dissolved Oxygen (DO)
• Conductivity
• Total Dissolved Solids (TDS)
• Salinity
• Turbidity
• Temperature
• Depth / Water Level
• Chlorophyll
• Blue-Green Algae
• Ammonium / Nitrate (optional sensors)

Features

• Rugged submersible construction for field deployment.
• Multiple sensors integrated into a single probe.
• Real-time monitoring and data logging.
• Digital sensor technology for improved accuracy.
• Low maintenance and easy calibration.
• Compatible with telemetry systems, PLCs, RTUs, and SCADA.
• Suitable for continuous online monitoring or portable applications.

Working Principle

Each sensor within the probe operates on its respective measurement principle (electrochemical, optical, conductivity, or optical scattering). The probe’s internal electronics process these signals and transmit the measured values through communication protocols such as:

• Modbus RS485
• SDI-12
• 4-20 mA
• HART
• Wireless Telemetry

Applications

• Water Treatment Plants (WTP)
• Sewage Treatment Plants (STP)
• Effluent Treatment Plants (ETP)
• Environmental Monitoring
• Surface Water Monitoring
• Groundwater Monitoring
• Aquaculture & Fisheries
• Industrial Process Water Monitoring
