Digital pH Measurement for Hygienic Processes
The CPS61E is designed specifically for applications where pH measurement needs to remain stable through repeated cleaning and sterilization cycles. It is suitable for food & beverage processes as well as bioreactors and fermenters in biotechnology and pharmaceutical production.
Its design provides reliable and reproducible pH measurement while supporting the demanding cleaning procedures commonly found in hygienic production.
Designed for CIP/SIP and Sterilization
A major advantage of the CPS61E is its suitability for CIP/SIP processes. Depending on the application version, the sensor can operate at temperatures up to 100°C and withstand sterilization temperatures up to 140°C.
This makes it particularly suitable for equipment that is regularly cleaned or sterilized without removing the sensor from the process.
Memosens 2.0 Technology
The CPS61E uses Memosens 2.0 digital sensor technology. Calibration and process information can be stored directly in the sensor, making sensor replacement and maintenance easier.
The sensor can also be calibrated away from the measuring point before being installed back into the process, helping reduce maintenance time and simplify sensor management.
Suitable for Bioreactors and Fermenters
For biotech and pharmaceutical production, the CPS61E is designed for pH measurement in bioreactors and fermenters, including applications such as enzyme production and culture growth control. Stable pH measurement can be an important part of maintaining controlled biological processes.
Hygienic Food & Beverage Applications
In food and beverage production, the CPS61E is particularly suited to CIP/SIP applications, where equipment is frequently cleaned and sterilized as part of the production process.
