5 Reasons

Accurate and stable

Anton Paar offers a range of different process CO₂ sensors. Depending on the sensor, the available accuracy varies from 0.1 g/L to 0.05 g/L. Count on stable readings with integrated temperature compensation that last a long time without any drift and reduce necessary adjustments to a minimum.


Anton Paar CO₂ Sensors keep your beverage quality on target by continuously monitoring their CO₂ content. A measurement starts once the process line is filled and then delivers short interval measurements, which can even be used for carbonator control loops.


With the Smart Sensors of the Carbo 5 series, everything is under control. The modular sensors available in three configurations all provide self-diagnosis in compliance with NAMUR recommendation NE107 and inform you when service is required or errors are detected. Alarms and limits are easily defined and messages are shown directly on the mPDS 5 evaluation unit or the sensor's operating terminal.
