Product Description
M4 Knick SE557 Refillable pH Sensor
The SE557 uses refillable liquid electrolyte for precise pH measurement in liquids with low ionic activity. Pressurization promotes electrolyte flow through its two ceramic junctions, helping keep the reference interface clean and stable.
Integrated temperature measurement supports compensation as process conditions change. Memosens and analog versions are available, with Alpha or Omega glass options selected according to the application. Temperature limits and hygienic suitability depend on the chosen configuration.
Applications
-
Boiler feedwater monitoring
-
Water for injection
-
Semiconductor manufacturing
-
Difficult liquids requiring stable pH measurements

-
Refillable electrolyte supports ongoing reference-system maintenance.
-
Pressurization helps resist contamination at the junctions.
-
Two ceramic junctions support consistent contact with the process.
-
Memosens versions provide an electrically isolated digital connection.
-
Calibration and diagnostic work can be performed away from the process installation.
