Endress+Hauser CCS50D-AA11AD | Memosens ClO2 Sensor, 0-5 ppm, Digital

Endress+Hauser CCS50D-AA11AD digital chlorine dioxide sensor. Memosens 2.0 technology, 0-5 mg/L trace range, amperometric, IP68, for drinking water & disinfection.

Product Overview

The Endress+Hauser CCS50D-AA11AD​ is a digital Memosens chlorine dioxide (ClO₂) sensor​ designed for precise disinfection control in water treatment. It operates on amperometric principle​ with a 0–5 mg/L (ppm) trace measurement range, ideal for drinking water and cooling tower applications. Featuring Memosens 2.0 digital technology, it ensures data integrity and supports predictive maintenance via contactless data transmission.

Key Features

  • Digital Memosens 2.0 Technology:​ Contactless inductive coupling prevents corrosion and moisture ingress; stores calibration data, sensor lifetime, and diagnostics directly in the sensor head.

  • Trace-Level Accuracy:​ Optimized for low-range 0–5 ppm ClO₂​ measurement with high sensitivity (nA/ppm), critical for drinking water disinfection compliance.

  • Robust Process Compatibility:​ PVDF membrane​ and POM/PVC body​ resist chemical attack from chlorine, ozone, and aggressive water matrices.

  • Plug & Measure:​ Pre-calibration in the lab allows quick sensor replacement without on-site recalibration, minimizing downtime.

Applications

  • Drinking Water Treatment:​ Disinfection control and residual ClO₂ monitoring in municipal waterworks.

  • Cooling Water Systems:​ Biofilm and legionella prevention in industrial cooling towers.

  • Food & Beverage:​ Process water disinfection and rinse water monitoring.

  • Wastewater & Reuse:​ Effluent disinfection and odor control.
