  • Drinking water

  • Swimming pool water

  • pH compensation for free chlorine measurement

Benefits

  • Reliable measurement at minimum conductivity thanks to three diaphragms

  • Low drift by very low level of ion depletion in electrolyte

  • Optional salt ring for extended operating time

  • 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

Videos

  • The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.

  • Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
