Odysséo – in situ probe for online measurement of UV COD SAC254

UV absorbance measurement (SAC 254) to determine the concentration of dissolved organic matter (COD, TOC, etc.) in less than a minute on any type of water, without filtration. 

Reliable measurement of dissolved organic matter

Measuring ranges:
0-100 Abs / m (river, drinking water)
0-1000 Abs / m (effluents, purification)

Measurement of SAC254 according to AFNOR XP T90-210 and DIN 38404-C3 standards

Definition of correlation curves for the measurement of COD, TOC and BOD on your application.

Quick results : measurement in 5 seconds without reagent

Reliable long-term measurement

Automatic cleaning system and zero correction.

No need for filtration

Optic turbidity compensation

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

Measure several parameters with a single probe

Thanks to a double optic cell, you can measure two parameters with a single probe (nitrate, color, …)
