Field of application
Orbipac CPF81D is the digital, simple solution for harsh environments. It measures reliably and accurately even in fibrous media and at high flow rates. With its integrated assembly, the electrode saves space and time during flow or immersion installation. Orbipac CPF81D is not the latest Memosens generation. To get information on the new Memosens CPF81E sensor with extended functionality, click here.
Orbipac CPF81D is the robust pH sensor for processes in mining industries and treatment of industrial water and wastewater. It monitors:
Flotation
Leaching
Neutralization
Inlet and outlet
Benefits
Suitable for flow and immersion installation
Long time stable: Second electrolyte bridge for better protection against electrode poisoning ions such as S2- or CN-
Robust polymer housing protects against mechanical damage
Optional flat membrane suitable for high flow rates and fibrous media
Maximum process safety through non-contact inductive signal transmission
Enables predictive maintenance due to storage of sensor and process-specific data
Reduced operating costs due to minimized process downtime and extended sensor lifetime
