Dissolved oxygen measurement

The Oxymax W COS21D is a digital dissolved oxygen (DO) sensor incorporating Memosens technology.

Using the Memosens technology, the DO sensor incorporates preventive maintenance capabilities.

Since the Memosens technology offers an 'intelligent' sensor with memory capacity, apart from standard data such as sensor ID and serial number, operational data is also recorded and made available for asset management.

This includes the number of calibrations, hours in operation, operating conditions such as temperature and current as well as SIP cycles and electrolyte concentration.

When a DO measuring point requires maintenance, a second sensor, which has been precalibrated in the laboratory or workshop, and the calibration data stored on the sensor, can then merely be 'swapped out' at the measuring point with the old sensor that was in need of maintenance, and the data is automatically uploaded into the transmitter.

The old sensor can then be cleaned and calibrated in the laboratory or workshop and placed on the shelf ready to be exchanged with the next sensor that needs maintenance.

Oxymax W COS21D is available in three versions. COS21D-A is suitable for monitoring cell cultures, for use up to 20 mg/L and is used primarily in fermentation systems.

COS21D-B is a trace DO sensor for media containing CO2, particularly in the drinks industry.
