The CO2 sensors available from Anton Paar continuously offer real CO2 values for any beverage and ensure an excellent total cost of ownership. The Carbo 6100 and Carbo 6300 models are EHEDG-certified and maintenance-free.
Apart from process monitoring, the 4-seconds measuring interval allows a stable and reliable closed-loop control of carbonators.
The Carbo 5100 model employs a well-established and proven measurement technology with highest reliability and accuracy, while requiring minimum maintenance about once a year.

Key Features
Zero Maintenance: Save Time and Money with the Carbo 6X00 Series
Users can save operation costs and achieve the lowest total cost of ownership (TCO). While the cost of traditional CO2 sensors can get multiplied over an entire service life because of repeated maintenance, the Carbo 6100 and Carbo 6300 models are fully maintenance-free:
- Self-diagnosis in compliance with NAMUR NE 107
- No moving parts with wear to exchange
The Carbo 5100 model must be serviced only once a year while running 24/7. The optional cut-off adapter can be used to remove it from the product line without cost-intensive and time-consuming production downtimes.

Product-Independent Measurement: Users can be Flexible with the Beverage Types
The Carbo series of sensors have the ability to handle any product type, even those that contain fruit pulp or fibers. The Carbo 5100 and Carbo 6100 models start quantifying immediately after a rapid selection of the appropriate product type. The Carbo 6300 model avoids the need for time-consuming product-specific adjustments.
Exclusive, patented compensation of sugars or extract allows product-independent operation. The Carbo 6300 model makes product changes easier for users irrespective of whether it handles sparkling water, beer, carbonated soft drinks, or wine.

Best Fit for Customers: Easy Integration and Automation in the Process
The new-generation CO2 sensors can be installed inline or in a bypass or tank, based on the needs of users. They can be combined easily into users’ workflow with the help of the touchscreen interface of the integrated evaluation unit, through the Pico 3000 software, or by using the mPDS 5 evaluation unit.

It is possible to adapt the sensors to support various communications protocols like EtherNet/IP, analog (4 to 20 mA), Modbus TCP, Modbus RTU, PROFIBUS DP, HART, and PROFINET IO.
Fast and Reliable Results Whatever the Conditions
The Carbo 5100 model has been designed in compliance with EHEDG guidelines and its established measurement principle offers accurate results at any time. The Carbo 6100 and Carbo 6300 optical sensors employ a patented technology that avoids the risks of inaccurate measurements, for example, after hot cleaning (CIP). The Carbo 6X00 range of optical sensors is EHEDG-certified, thus reducing the time and effort needed for cleaning processes.

Speed Meets Excellence: Get Results Within Seconds
The Carbo series of sensors feature a measuring interval of only a few seconds, thus known to be the fastest commercially available CO2 sensors, which are also ideal for closed-loop control of carbonators.
The Carbo 5100 and Carbo 6X00 optical sensors enable users to always find the actual CO2 concentration of all beverages in their process, ensuring the highest repeatability and accuracy even under start/stop conditions. The optical sensors offer accurate measurements even during long flow stops, directly in the production line.
