Mr HàOn-line Turbidimeter (ISO 7027) with free fall flow cell with high resolution
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
