Dissolved CO₂ directly affects a beverage’s taste, mouthfeel, shelf life, and regulatory compliance. Whether you produce beer, soda, or sparkling wine and water, determining your carbonation levels is critical to maintaining product quality and customer satisfaction. A CO₂ meter provides precise, repeatable data – far beyond what traditional manual methods or visual checks offer.

• Prevent under- or over-carbonation during production
• Maintain batch consistency and brand profile
• Avoid costly rework or recalls due to carbonation deviation
• Ensure compliance with international labeling and packaging standards

• Over-carbonation can cause excess foam, burst containers, wasted product, and unnecessary costs.
• Under-carbonation leads to flat taste, poor sensory experience, and brand dissatisfaction.
• Many regulatory and quality frameworks require the actual CO₂ content to align with the declared value.
• Inconsistent CO₂ levels can trigger costly recalls or lead to rejected shipments.

Reliable CO₂ testing is no longer a “nice-to-have” – it's a non-negotiable requirement in modern beverage QA.

Dissolved CO₂ refers to the carbon dioxide absorbed into a liquid. In beverage production, controlling this parameter ensures proper mouthfeel, taste, and shelf stability. Anton Paar’s portable CO₂ meters are the only instruments that use a precise, selective Multiple Volume Expansion method to measure true dissolved CO₂, unaffected by other gases and reflective of actual product conditions. This ensures that your products maintain the target sensory profile your customers expect. Results are delivered in units, such as g/L and vol., depending on your QA standards.

While fixed analyzers have their place, portable CO₂ meters offer unmatched flexibility for modern beverage producers. They eliminate bottlenecks, reduce sampling time, and enable quick decision-making exactly where it matters – at the line, in the cellar, or during packaging.

• Selective, precise CO₂ analysis – no interference from other gases
• Works with bottles, cans, kegs, tanks, and lines
• Low sample volume required – starting from 100 mL
• Compact, IP67-protected design for harsh environments
• Digital data storage and integration via AP Connect

A portable CO₂ meter is a compact, field-ready instrument designed to measure dissolved carbon dioxide in beverages and production processes. It delivers lab-quality results in real-world conditions – without the need for large equipment or specialized lab staff. Monitor and record carbonation on the go at multiple points in your production with our portable measuring instruments.

Anton Paar’s portable CO₂ meters use a proven Multiple Volume Expansion method to deliver the selective and precise CO₂ measurements. This measuring principle provides repeatable results – unaffected by other dissolved gases – and is trusted by QA professionals in both small-scale and global production settings.

Common use cases:

• Quality control of final product
• In-process spot checks in production
• Tank monitoring
• Verification and troubleshooting of equipment
• Product development and pilot trials
