4670 Series

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. Flexible installation — Immersion and flow-through sensors — Wall and panel mount transmitters Automatic sensor cleaning — Reduces maintenance requirements — Optimizes performance sensitivity Secondary standards for calibration verification — Accurate, repeatable, safe, simple — Realize significant cost savings by reducing the use of primary standards Reliable and accurate measurement — In-built sensor diagnostics — Automatic bubble rejection to compensate for erroneous readings due to degassing
