Inline Beverage Analyzer:
Cobrix 5500/5600

  • 360°

Intelligent multi-parameter measurement solution for beverage production

The new Cobrix 5500 and Cobrix 5600 provide continuous measurements of °Brix, %Diet, and CO2 during soft drink production. Being pre-adjusted in the factory, they do not require time-consuming, product-specific on-site adjustments and commissioning procedures. Besides measuring °Brix, %Diet, and CO2 concentration, various other parameters, such as alcohol content, sugar inversion, and optionally also conductivity, color, and oxygen, can be determined.

They use digital signal processing and new mechanical design to deliver stable, drift-free results and help keep your production highly efficient.

Key features

Two system configurations to suit your application

Cobrix 5500 

Density and sound velocity sensor combined with a p/T (volume expansion) CO2 measurement

  • Low maintenance – depending on the operating conditions maintenance is required on average every 6 to 18 months
  • Product-specific setups at the best value
  • W-shaped oscillating tube
  • Digital signal processing
  • New mechanical design for reduced size and weight

Cobrix 5600 

Density and sound velocity sensor combined with an optical CO2 measurement

  • Product-independent measurements (whatever your beverages’ solubility, sugar composition, foreign gases, color, or turbidity: nothing influences your readings)
  • Suitable for hygienic applications
  • Maintenance-free
  • W-shaped oscillating tube
  • Digital signal processing
  • New mechanical design for reduced size and weight


Rapid production start

Save time and costs during commissioning and production downtimes, and accommodate a wide range of soft drinks with little or no adjustment. Anton Paar’s Cobrix models give you the flexibility to react to product and market demands instantly.


Safeguard your production – maintain your product quality

Continuous measurement of all your product parameters, including °Brix, %Diet or TA, CO2, alcohol, sugar inversion, and more, ensures that your production and your product is within specifications.


Ease of use

A simple touchscreen user interface facilitates the setup of the instrument and product parameters. In addition, you can visualize your process and display graphical trends with just a few clicks. By setting lower and upper limits on measurement values, alarms can be set and triggered using digital or relay outputs.


Optimal use of raw materials due to accurate parameter measurements anytime

  • Compensate for sugar inversion
  • Determination of actual °Brix, °Brix fresh, and °Brix inverted


Fits your production environment

  • Inline or bypass version, depending on your special production conditions
  • Evaluation unit can be installed up to 250 meters away from the sensor to facilitate access to production data
  • Standard Ethernet connection to Davis 5 software to visualize statistical and production data and trends from all around the production plant and also connect to lab equipment, if applicable
  • Various communication possibilities: classic analog outputs (4 mA to 20 mA), digital-IOs, and various fieldbuses available (PROFIBUS DP, Modbus TCP, PROFINET, DeviceNet, or EtherNet/IP)


Improved process capability – keeping an eye on all relevant key parameters

The powerful data acquisition and visualization software (client-server) Davis 5 enables you to save all data and alarms, provides statistical process control and graphical trend analysis, and allows product adjustments. Password-protected access to all measuring systems is possible from various locations, while providing powerful reporting and integration with your corporate quality management system.
