AquaScat - In-line Turbidity Meter for Water
The AquaScat measures turbidity of potable water according to IEC 27027 using 90+° scattered light detection in a free-falling water stream (models WTM, WTM A, HT). 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).
Applications
- Turbidity measurement in raw water
- Monitoring of flocculation and dosage of flocculants
- Filtration monitoring of filter performance and back-wash control
- Turbidity measurement in treated and final waters
- Turbidity monitoring of water in storage and distribution networks
- Turbidity measurement in process and waste waters
Features & Benefits
- True non-contact measurement in free-fall stream (models WTM, WTM A, HT) making it virtually maintenance free
- Dual beam measurement in optimized cell (model P)
- Re-calibration with secondary standard (fully automatic at model WTM A)
- Lowest stray light levels
- Convenient operation via touch screen
- Graphical display of trends and/or values
- Visualization of measured values over the previous month
