The Carbo 520 Optical sensor for beverages from Anton Paar is a directly in-line, robust, hygienic sensor that is entirely maintenance-free.
The Carbo 520 is a “fit-and-forget” system that provides linear, drift-free CO2 readings over the entire measurement range from 0 g/L to 12 g/L.
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.
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 same measurement method whether they wish to determine the CO2 content of soft drinks, beers, wines or other beverages.
