The Orbipac CPF81D is a digital electrode and a simple solution for measurements under harsh operating conditions. It provides reliable, high-precision measurement even in fibrous media and at high flow rates. The integrated assembly saves space and time when installing the electrode in flow or immersion installations. Using Memosens digital technology, the CPF81D offers maximum process and data integrity and is easy to operate. The electrode is corrosion-resistant and moisture-proof and can be calibrated in the laboratory and used for preventive maintenance.

Advantages
Suitable for flow and immersion installations
Long-term stability: a second electrolyte bridge provides better protection against electrode poisoning, e.g. by S2- or CN- ions
Robust polymer housing protects against mechanical damage
Flat diaphragm suitable for measurement in high-flow and fibrous media
Non-contact inductive signal transmission ensures maximum process safety
Stores sensor characteristic data for convenient preventive maintenance
Reduces process downtime, extends electrode service life and lowers operating costs

Application areas
The Orbipac CPF81D is a rugged pH electrode for measurements in mining processes and water & wastewater treatment processes. It monitors:
Flotation
Leaching
Neutralization
Inlet and outlet
