Multi-Parameter Water Quality Sensor
The multi-parameter water quality sensor is designed to work seamlessly with Instrava multifunction water quality analyzers.
A single integrated probe enables simultaneous measurement of up to seven key water quality parameters, significantly reducing installation space, wiring complexity, and maintenance workload.
With digital RS-485 (Modbus RTU) output, automatic cleaning capability, and wide power supply compatibility, the sensor is ideal for continuous online monitoring in water treatment, chemical processes, environmental monitoring, and industrial wastewater applications.
Transmitters & Sensors Description
7-in-1 Digital Sensor-Measured Parameters
This integrated sensor supports the following parameters within one compact structure:
pH
Dissolved Oxygen (DO)
Turbidity
Conductivity / Salinity
ORP (Oxidation Reduction Potential)
Temperature
All parameters are measured simultaneously and transmitted digitally to the analyzer.
Working with Water Quality Analyzer
The sensor is specifically designed for integration with Instrava multifunction water quality analyzers.
All measured parameters are digitally transmitted via RS-485, ensuring:
Stable signal transmission over long distances
No signal drift compared with analog sensors
Simplified wiring and commissioning
One analyzer can display, transmit, alarm, and log all parameters simultaneously.
Multi-Parameter Water Quality Sensor Key Advantages
7 parameters in one sensor – compact and space-saving
Digital RS-485 output – strong anti-interference performance
Automatic cleaning function – reduced maintenance frequency
Unified power supply – easy system integration
Factory-matched analyzer compatibility – plug-and-play deployment
Multi-Parameter Water Quality Sensor Typical Applications
Municipal water treatment plants
Industrial wastewater treatment
Chemical process water monitoring
Environmental monitoring stations
Power plants and energy facilities
Food & pharmaceutical water systems
