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.
