The AquaScat measures turbidity of potable water according to IEC 27027 using 90+° scattered light detection in a free-falling water stream. This contactless design eliminates window foiling and minimizes servicing to a minimum. Calibration check is performed with a calibration unit that is either mounted to perform the check or that is already built in (depending on variant).

  • True non-contact measurement in free-fall stream
  • Re-calibration with secondary standard (fully automatic)
  • Lowest stray light levels
  • Extremely low maintenance
  • Convenient operation via touch screen
  • Graphical display of trends and/or values
  • Visualization of measured values over the past month
