SE 559

pH Sensor


For uncomplicated measurement in water and analytical chemistry, digital, with Memosens technology.

Facts and Features

  • Perfect galvanic isolation thanks to Memosens technology
  • No influence of humidity in the connector
  • Precalibration in the lab
  • Digital data transfer
  • Integrated sensor diagnostics
  • Low maintenance, no refilling of electrolyte
  • Integrated temperature detector
  • Calibrated annular junction
  • Independent of flow
  • Alpha glass, medium impedance,
    universal glass, fluoride resistant

The calibrated annular junction enables precise measurements in process media virtually without influence of flow. 

The large contact surface of the junction minimizes problems caused by contamination. The sensor is ideal for processes for which liquid-electrolyte sensors should be used, but where maintenance is impossible for a longer period of time.
