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.
