The oxygen content is a crucial parameter for the taste and shelf life of beverages. The Oxy 5100 inline oxygen sensor measures dissolved oxygen (DO) in real-time directly at the production line. It provides accurate, drift-free measurements throughout the entire production process.

Oxy 5100 can easily be combined with additional process sensors from Anton Paar to meet all future production and quality control requirements.

Key features

One sensor for two different measuring ranges

One sensor for two different measuring ranges

Oxy 5100 performs highly accurate measurements in the trace range (0 ppb to 2000 ppb) as well as in the wide range (0 ppm to 24 ppm). Switching between the ranges is conveniently done by simply exchanging the sensor cap.

No worries about cap calibration due to clever sensor caps

No worries about cap calibration due to clever sensor caps

All required calibration parameters are stored in the sensor cap. The Toolmaster® technology automatically detects the sensor cap and transfers all setup parameters to the sensor. Once the cap is mounted, inline measurement can start immediately.

Lifetime Estimator: Easy planning of sensor cap exchange

Lifetime Estimator: Easy planning of sensor cap exchange

Replacement of a sensor cap is a predictable work step that should be planned and integrated into regularly scheduled downtimes. The Lifetime Estimator of Oxy 5100 estimates the remaining service life of the sensor cap in days and warns you when a new sensor cap is required.

Hygienic design – EHEDG-certified

Hygienic design – EHEDG-certified

Oxy 5100 fulfills international hygienic standards as it is EHEDG-certified Type EL – Class I and can be cleaned using CIP procedures. All materials which are in contact with the sample are FDA-compliant. Oxy 5100 is suitable for hygienic applications in the beverage, pharmaceutical, and water treatment industries. The sensor is quickly back to work after CIP, thus reducing downtimes.

Plug and play – easy setup with maximum compatibility

Plug and play – easy setup with maximum compatibility

No special training is required to commission and operate the instrument. Oxy 5100 is set up quickly and easily using the touchscreen interface of the built-in evaluation unit, via the Pico 3000 software, or with the help of the mPDS 5 evaluation unit.

Oxy 5100 can be easily adapted to support several communications protocols including analog (4 mA to 20 mA), Modbus RTU, Modbus TCP, HART, PROFIBUS DP, PROFINET IO, and EtherNet/IP.
