Endress+Hauser Memosens COS22E

Digital oxygen sensor

Memosens 2.0 hygienic, amperometric oxygen sensor for the food and life sciences industries.

Amperometric oxygen measurement

Typical applications are:
- Pharmaceuticals and biotechnology: process control in enzyme production, control of culture preparations
.
- Water treatment: boiler feed water, WFI (Water for Injection)
- Residual oxygen measurement in processes

Installation
