SE 554 pH Sensor


The SE 554 Memosens pH sensor is ideal for use in liquids with suspended solids and high ionic strength. This sensor is constructed using Alpha pH glass, 2 open hole junctions & a solid polymer electrolyte with high KCl concentration. These features provide stable performance and long life in the most difficult applications.


The integrated NTC 30K temperature element assures that all pH measurements are accurately compensated.


The robust sensor design & construction, along with the integration of Memosens technology, provide for a significant reduction in overall cost of ownership.
