pH sensors

Safe and reliable pH measurements

Designed to achieve high measurement reliability with minimum effort, Memosens glass sensors have a very stable signal with 100% integrity and hold their specific characteristic information, stored inside a microchip.

Memosens technology

Memosens converts the measured value to a digital signal and transfers it inductively to the transmitter, eliminating the problems associated with moisture and corrosion – the sensors could even be operated under water. Patented by Endress+Hauser in 2004, Memosens technology revolutionized operation and maintenance in the field of liquid analysis.

What our customers say



Calibration in the lab, plug & play in the process


Measured values are converted within the sensor, which sends a stable, digital signal to the transmitter


Memosens meters correct for temperature fluctuation and are corrosion-resistant 


Longer sensor lifetime due to best suitable material for each application

Industries and applications

Endress+Hauser offers a wide selection of electrodes, specifically designed for the use in the following industries:


Portable transmitter Liquiline To Go 
The robust multiparameter handheld enables you to control any measuring point in your plant with the identical Memosens sensors that you use in your process.  
Measure pH, temperature, conductivity, oxigen or oRP depending on the type of sensor you connect as long as your sensors are digital.

Endress+Hauser also offers a variety of multichannel field transmitters, as well as oxygen, conductivity, ORP, and other types of sensors and instrumentation for liquid analysis.

Why pH measurements matter?

Quality and safety

  • In some processes, the product measured will be used for human consumption, and pH directly or indirectly affects taste, edibility, and other important safety factors.
  • Some products’ entire existence comes down to a change in pH.

Cost efficiency

  • You can leverage energy costs in many processes by having a controlled value of the liquid (steam applications, oil separation, etc.)
