AquaScat 2 WTM
On-line Turbidimeter (ISO 7027) with free fall flow cell with high resolution
- 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
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).
