Carbonation Tester: Ensuring Accurate Beverage CO₂ Measurement

A carbonation tester is an essential instrument for measuring the CO₂ content in beverages, ensuring product consistency, freshness, and taste quality. In drinks such as soft drinks, sparkling water, beer, and fermented beverages, proper carbonation impacts mouthfeel, texture, and shelf-life. Using a carbonation tester allows beverage manufacturers and quality control teams to maintain production standards, minimize batch inconsistencies, and satisfy consumer expectations.

ASTM F1115 and Beer Carbonation Levels

The ASTM F1115 standard provides a widely recognized method for measuring carbonation in sealed beverage containers, including beer, soft drinks, and sparkling water. This standard ensures consistent and accurate determination of beer carbonation levels and overall CO₂ content, which is critical for maintaining product quality, flavor, and shelf-life.

Key Aspects of ASTM F1115:

Test Purpose:

  • To quantify the CO₂ volume in a beverage container.

  • To monitor carbonation loss during storage or shipment.

  • To ensure that beverages meet consumer expectations for taste, mouthfeel, and effervescence.

Testing Procedures:

    • Procedure A: Laboratory method using precise pressure and temperature monitoring equipment, ideal for R&D and product development.

    • Procedure B: Simplified method using manual or automated carbonation analyzers, suitable for production and quality control.

Measurement and Calculations:

  • Records internal pressure and temperature of beverages.

  • Calculates CO₂ volume using solubility data and ASTM F1115 tables.

  • Determines if the beverage meets desired carbonation specifications.

Significance for Beer and Carbonated Beverages:

  • Ensures consistent carbonation levels, preventing flat or over-carbonated products.

  • Provides data for product development, helping beverage formulators optimize recipes and packaging.

  • Supports regulatory compliance and internal quality standards.

Test Process Overview

The Cell Instruments CLRT-01 carbonation tester streamlines CO₂ measurement through an automated and precise workflow:

  1. Automatic Cap Piercing – The device penetrates the bottle cap at a controlled speed, maintaining internal pressure.

  2. Pressure Stabilization – Vent valves adjust internal pressure to establish a baseline for measurement.

  3. Agitation for Uniform CO₂ Distribution – Servo-driven rotation ensures carbonation is evenly mixed throughout the beverage.

  4. Real-Time Data Capture – High-resolution sensors record pressure (MPa) and temperature (℃) continuously.

  5. CO₂ Volume Calculation – The embedded algorithm automatically calculates carbonation volume and displays results instantly.

This workflow eliminates human error, reduces testing time, and guarantees repeatable, reliable measurements suitable for both laboratory and production environments.
