The Memosens CPS47D digital ISFET electrode offers superior performance for measuring low conductivity or high concentrations of organic solvents in process applications where glass breakage is prohibited. The short response time of the electrode enables highly accurate measurement even in applications with rapidly changing media. The sensor shaft cannot break, ensuring maximum product safety. In addition, Memosens digital technology offers maximum process and data integrity with simple operation. The electrode is moisture- and corrosion-resistant and can be calibrated in the laboratory for predictive maintenance.
Benefits
The sensor cannot break, ensuring maximum product safety
Stable KCl salt bridge electrolyte filling and independent reference lead for high resistance to poisoning
Suitable for steam sterilization
Long calibration intervals, low maintenance
Non-contact inductive signal transmission for maximum process safety
Storage of sensor and process parameters enables predictive maintenance
Minimal downtime reduces operating costs and extends sensor service life
Applications
Media with high concentrations of organic solvents or extremely low conductivity:
• Chemical industry, measurement of media prone to clogging
• Power plants, e.g. boiler feed water
• Life sciences, e.g. water for injection
Certified for all relevant hygienic applications, e.g. EHEDG, 3A, EU1935/2004, USP 87/88.
