The Memosens CPS76E is the measurement specialist for demanding conditions and can measure pH and ORP simultaneously. The unique contamination-resistant reference system reliably measures heavily contaminated media and low-conductivity media. The CPS76E uses Memosens 2.0 digital technology with high process integrity and very simple operation. The waterproof, moisture-proof design allows laboratory sensor calibration and supports extended data storage for calibration and process parameters. It is the perfect basis for predictive maintenance.
Benefits
Memosens 2.0 supports an extended storage unit for calibration and process parameters, enabling better trend identification and providing the perfect basis for future predictive maintenance and improved IIoT services.
Simultaneous measurement of pH, ORP and rH values (in rH mode) provides rich process information and is a solid foundation for strict process control.
Optional pressurized reference system for reliable measurement of media prone to clogging, such as dispersions.
The electrode has a dedicated ion trap that effectively prevents toxic diffusion to the lead and reference system, ensuring a long service life.
The electrode can be installed upside down for flexible installation.
Non-contact inductive signal transmission for high process safety.
Minimizes production downtime, extends electrode service life and reduces operating costs.
Applications
Chemical process and process monitoring:
Rapidly fluctuating pH or ORP values
Highly toxic media, e.g. H2S
Approved by ATEX, IECEx, CSA C/US, NEPSI, JPN, INMETRO for use in explosion-protection zones 0, 1 and 2.
