SEM Proteus Meter

The Proteus meter is the world’s first scientifically proven real-time sensor that has up to 13 sensors and can measure 30+ contaminants.  This means that the meter can be utilised for a wide range of applications.

How does it work?

The technology allows for real-time data measurement of parameters such as Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and many others.

It is a multi-probe that measures your choice of parameter, all in one package, that can deliver data in the toughest field conditions. The technology is designed for ease of use, reliable data and economical operation.

The meter can measure the following parameters:

  • BOD
  • Dissolved Oxygen
  • Pressure
  • Chloride
  • pH
  • Temperature
  • Optical Brighteners
  • Nitrate
  • Faecal coliforms
  • Trypophan
  • Refined Oils
  • Ammonium
  • EC/ Salinity / TDS
  • Turbidity
  • Crude Oils CDOM
  • COD
  • TOC


  • Self cleaning
  • Improve process control
  • Simple to use and intuitive software
  • Multiple sensors can be added
  • Robust build quality with stainless steel and Derlin outer casing
  • Maintenance free
  • Multiple power options (battery pack, external power source)
  • Easy integration
  • Measure bacteria / coliforms in drinking water
