The Memosens CPL51E is rugged and durable, with a plastic electrode shaft, protected glass membrane and no metal lead, allowing direct water sample analysis in the field or in the laboratory. The precalibrated electrode is plug and play. It is recommended for use with the Liquiline Mobile CML18 mobile handheld device, without any further settings.
Benefits
Inductive Memosens sensor connection is unaffected by moisture and corrosion.
Measuring point checks can be performed in the laboratory or on site. The physically protected glass membrane works safely in water and wastewater conditions.
Built-in temperature sensor with automatic temperature compensation.
Fast response, even in cold water with poor ionic activity.
Reference system with open junction minimizes the risk of clogging.
Application areas
Memosens CPL51E is suitable for drinking water, wastewater and process water applications:
Online checking of measuring loops
Analysis of water samples (on site or in the laboratory)
Offline pH measurement
