Memosens 2.0 for reliable pH measurement
Sensors reduce maintenance effort in food processing
For a potato processing plant in the East of England, being able to accurately measure the pH content of water is vital. Their chips are blanched in a vessel of hot water before being dried and fried, and the water quality can affect the look and taste of the product. The plant’s existing ISFET pH sensors were about to become obsolete, so a new solution was needed.

Our solution
Endress+Hauser provided the manufacturer with two new pH sensors, Memosens CPS77E and CPS97E, for evaluation.
The new sensors have proved their worth with regard to stability and general measuring performance, and the customer was particularly impressed by the reduced maintenance effort required:
“We have noticed that the 97 in particular doesn’t need to be calibrated very often. It just needs a quick clean and it doesn’t seem to drift. It’s ideal for our process.”
