Digital combined pH/ORP sensor Memosens CPS16D

Memosens glass electrode for standard applications

Memosens CPS16D is the digital all-rounder for simultaneous pH and ORP measurement offering better process control and increased quality. The sensor features a dirt-repellent PTFE diaphragm for process and environment applications with long-term stable conditions. Thanks to Memosens digital technology, CPS16D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.


  • Simultaneous measurement of pH, ORP and rH values (in rH mode) for a better process overview
  • Additional platinum electrode enables constant monitoring of reference impedance and thus sensor quality
  • Robust and resistant to poisoning thanks to large PTFE ring diaphragm and reference with ion trap
  • Suitable for harsh applications: Process glass for highly alkaline media and pressure-stable up to 17 bar (246 psi)
  • Enables predictive maintenance due to storage of sensor and process-specific data
  • Reduced operating costs thanks to minimized process downtime and extended sensor lifetime

Field of application

  • Long-term monitoring or limit control in processes with stable process conditions:
    - Chemical processes
    - Pulp and paper industry
    - Power stations (e.g. flue gas cleaning)
    - Incinerator plants
    - Mining
    - Wastewater
  • Water treatment:
    - Drinking water
    - Cooling water
    - Well water

With ATEX and IEC approval for use in hazardous areas.
