Proteus Multi-parameter Water Quality Sensor

Water Quality Monitoring

Water Quality Monitoring System is to monitor multiple water quality parameters with a fully integrated, easy to use and with economical system. Water quality sensors in our range of product are customizable and capable for measuring wide variety parameters. Parameter include: Temperature, pH, Conductivity, Turbidity, Dissolved oxygen, Ammonia, Hydrocarbon, BOD, TOC and many more.


An award-winning, patented, multi-parameter, real-time sensor platform to accurately and reliably measure BOD, COD, TOC and Coliforms (total, E. coli or faecal) in permanent and temporary applications. The Proteus is the world’s first scientifically proven real-time sensor for measuring BOD that can measure a wide range of water quality, environmental and industrial applications. A multiprobe that measures your choice of parameter, all in one package, that can deliver data in the toughest field conditions. The Proteus has been designed for its ease of use, reliable data and economical operation.

Parameters include:

BOD, COD, TOC, DOC Optical Brighteners Ammonium
Dissolved Oxygen Nitrate EC / Salinity / TDS
Pressure ORP / REDOX Turbidity
Chloride Coliforms (faecal, E. coli, total) Crude Oils
pH Tryptophan CDOM
Temperature Refined Oils

A range of power options are available including internal lithium battery packs, ideal for unattended logging, or multiple external power options of battery, mains or solar panel.
