Physeo – continuous analysis of physico-chemical parameters

Compact transmitter for online measurement of physico-chemical parameters in water : pH, conductivity, dissolved oxygen, temperature, water level, etc.

Up to 4 parameters simultaneously

Simple adjustment and use

An integrated computer provides supervision of the measurement functions, which makes the various adjustment operations very simple.

Measurement results in the unit of your choice

for example in ppm DO2or% sat DO2 for dissolved oxygen.

Automatic probe cleaning

For each probe, an automatic cleaning cycle can be defined. This cycle consists of the controlled activation of a control relay of an external cleaning system.

An economical measurement system


Very low operating cost and reduced need for maintenance

  • No reagent for the measurement.
  • No need for calibration solution.
  • Automated cleaning system and zero adjustment.
  • Automatic calibration from a standard.

Equip your facility for a long time with analyzers built to last

In contrast with planned obsolescence, our devices are built to last, to be easily maintained and repaired when needed.
Make significant savings in money and time over the long term :


  • Product design and component sourcing driven by sustainability
  • Helpful and responsive support and maintenance service
  • 2 year manufacturer’s warranty
