Digital non-glass pH sensor
Tophit CPS491D

Tophit CPS491D - Digital non-glass pH electrode for heavily soiled media ©Endress+Hauser

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.

Memosens ISFET sensor for heavily polluted media in chemical processes, paper or paint production

Tophit CPS491D is the specialist for fibrous media or media with a high content of suspended solids such as dispersions, precipitation, emulsions. Its unbreakable shaft ensures a long operating life while the open aperture guarantees reliable measurement under harsh process conditions. Thanks to Memosens digital technology, CPS491D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.
