In-line turbidity measurement for the water treatment

The AquaScat measures the turbidity of potable water according to IEC 27027, with the measurement carried out directly in the water. This reduces maintenance work to a minimum. The calibration is done with a checking unit that is installed when needed. Various customer wishes can be catered for with the different options for data visualization and connection to a PLC/SCADA. Thanks to the different process integration options, a solution can be found for virtually any requirement.

• Measurement directly in the water
• Recalibration with secondary standard – Precise re-calibration is possible
• Lowest stray light level, also in heavily reflecting stainless steel tubing
