4670 Turbidity Systems Datasheet

ABB’s 4670 series turbidity systems are available as in-situ dip systems suitable for turbidity measurement in open channels and tanks or as a flow-through design suitable for water applications that have high turbidity values. Measurement ranges are configurable between 0 to 100 FTU up to 0 to 2000 FTU. All systems are provided with ABB’s auto-cleaning function and available with dry secondary calibration standards for accurate reliable turbidity measurement with reduced cost of ownership.
