The Memosens CPF81E is a digital pH electrode that is robust and measures pH values stably under demanding conditions. Measurement is completely unaffected even by corrosive media and high-flow media. The electrode has its own holder and requires little installation space. The CPF81E uses Memosens 2.0 digital technology with high process integrity and very simple operation. The electrode is waterproof and moisture-proof and allows laboratory calibration. It supports extended data storage for calibration and process parameters, making it 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.
High long-term stability: double-junction design for better protection against ion toxic diffusion, e.g. S2- or CN-.
Robust polymer housing effectively prevents mechanical damage.
The optional flat membrane allows measurement in high-flow and abrasive media.
Non-contact inductive signal transmission for high process safety.
Minimizes production downtime, extends electrode service life and reduces operating costs.
Applications
The Memosens CPF81E pH electrode is robust and suitable for mining industry applications as well as water and wastewater treatment. It reliably monitors:
Flotation processes
Leaching processes
Neutralization processes
Inlet and outlet
Approved by CSA C/US for use in explosion-protection zones 0, 1 and 2.
