CT200 – online UV-COD analyzer – 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 the need for filtration.

Reliable measurement of dissolved organic matter

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

SAC254 measurement according to AFNOR NF T90-210 November 2018 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.

Functional on dirty water

Large-scetion hoses limit the risk of clogging.
Optical 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.
