A new kind of certainty in beverage production

A new process CO2 sensor for beverage from Anton Paar.

Carbo 520 Optical from Anton Paar is a new process CO2 sensor for beverages. Easily installed, directly in-line, this robust, hygienic (EHEDG approved) sensor is entirely maintenance-free.

The Carbo 520 is a truly “fit-and-forget” system that provides linear, drift-free CO2 readings over the entire measurement range from 0 g/L to 12 g/L – and gives way to a new kind of certainty in CO2 monitoring throughout the beverage production process.

The basis of this breakthrough: a cutting-edge optical measuring principle called ATR.

The Carbo 520 Optical measures CO2 concentration based on the spectroscopic approach of Attenuated Total Reflection (ATR), so the only “motion” in the system is the passing of infrared light through a crystal. Since the sensor has no moving or mechanical parts, there is no wear & tear and no consumables are required.

Since the sensor measures only specific wavelengths of light absorbed by CO2 molecules, the Carbo 520 provides the true CO2 results, uninfluenced by foreign gases such as air, nitrogen or oxygen. The measurement is performed at the surface layer of a sample, therefore its individual color or turbidity is irrelevant to the measured results. In addition, the Carbo 520 Optical’s results are independent of the measured beverages’ solubility and sugar composition. This means that users can apply the exact same measurement method whether they wish to determine the CO2 content of soft drinks, beers, wines or other beverages. No beverage type differences need to be considered.

Carbonation is a key element to the taste and perceived freshness of a beverage. For complete control of this parameter in production, where beverage producers naturally seek to minimize their raw material investment and run their production tightly within specifications, the concentration of dissolved CO2 is ideally measured continuously and directly in-line.
