Overview of Carbonation Tester for Beverages

A Carbonation Tester for Beverages is used to determine the dissolved carbon dioxide (CO₂) level in carbonated beverages by measuring pressure and temperature and correlating the results with established carbonation tables. Accurate carbonation measurement is important for beverage manufacturers because CO₂ concentration directly influences product consistency, mouthfeel, freshness, foaming behavior, and consumer perception. For laboratories and production facilities working with carbonated soft drinks, sparkling water, beer, and other beverages, choosing the appropriate testing method can significantly affect testing efficiency and repeatability.

Cell Instruments offers two different solutions for this application: the CLRT-01 Carbonation Tester for Beverages a CLRT-02 Manual Carbonation Tester for Beverages. Both instruments are designed for beverage carbonation testing and support applications related to ASTM F1115 a GB/T 10792, but their operating principles and levels of automation are different.

The CLRT-01 focuses on automated and repeatable carbonation measurement, while the CLRT-02 provides a manual and cost-effective testing solution. Understanding these differences helps laboratories, beverage manufacturers, and purchasing managers select the appropriate carbonation testing equipment.

What Does a Carbonation Tester for Beverages Measure?

Carbonated beverages contain CO₂ dissolved in the liquid under pressure. The amount of dissolved CO₂ changes with temperature and pressure, so carbonation measurement requires both parameters to be considered.

A Carbonation Tester for Beverages typically measures:

The measured pressure and temperature values can then be correlated with an appropriate carbonation table to determine the beverage’s CO₂ volume.

For example, two beverage samples may produce different pressure readings even when they contain similar amounts of dissolved CO₂ if their temperatures are different. Therefore, temperature control or accurate temperature measurement is an important part of reliable carbonation testing.

This makes carbonation testing useful for:

Why Is Carbonation Testing Important for Beverages?

Carbonation is an important quality characteristic for many beverages. Too little CO₂ may produce a flat or weak sensory profile, while excessive carbonation can affect foaming, filling behavior, package pressure, and consumer experience.

Routine carbonation testing allows manufacturers to establish measurable quality limits instead of relying only on sensory evaluation.

Typical applications include:

Beverage TypePurpose of Carbonation Testing
Carbonated soft drinksVerify target carbonation level
SodaMonitor batch-to-batch consistency
Sparkling waterConfirm dissolved CO₂ content
BeerEvaluate carbonation consistency
Craft beveragesSupport product development and QC
Fermented beveragesMonitor carbonation characteristics
Energy drinksVerify production specifications

For laboratories, a standardized measurement method also provides a more objective basis for comparing samples.

CLRT-01 vs. CLRT-02 Carbonation Tester for Beverages

The main difference between the two carbonation testers is their level of automation. The CLRT-01 is designed for automatic carbonation testing, reducing manual intervention during the testing process. The CLRT-02 is a manual carbonation tester, requiring the operator to manually perform the testing steps.

In short, CLRT-01 focuses on automated testing, while CLRT-02 focuses on manual testing. Both use the same basic pressure-and-temperature principle for evaluating beverage carbonation.

Carbonation Tester for Beverages: CO₂ Testing Method and ASTM F1115

Automatizované testovanie karbonizácie pomocou CLRT-01

Stránka CLRT-01 is designed for users who need a controlled and repeatable carbonation testing workflow.

Instead of requiring the operator to manually perform every step, the instrument uses a PLC-controlled system and servo motor to standardize the test sequence.

The typical workflow includes:

Automatic Piercing → Pressure Stabilization → Agitation → Pressure & Temperature Measurement → CO₂ Calculation

1. Automatic Cap Piercing

The CLRT-01 automatically penetrates the beverage container cap at a controlled speed. The default piercing speed is 5 mm/s, while other settings can be configured according to the application.

Automatic piercing helps reduce differences between operators and provides a more consistent starting condition for each test.

2. Pressure Stabilization

After piercing, the system uses the vent valve to release excess gas and establish a suitable measurement condition.

Stable pressure is important because an unstable reading can affect the final carbonation calculation.

3. Servo-Driven Agitation

The instrument uses a servo-driven mechanism to agitate the beverage sample. The default shaking time is 40 seconds, while the operating parameters can be customized.

Agitation helps redistribute dissolved CO₂ and promotes a more uniform condition before measurement.

This automated agitation is one of the major differences between the CLRT-01 and a manual soda Carbonation Tester for Beverages

4. Real-Time Measurement

The CLRT-01 records pressure and temperature during testing.

Its specifications include:

The measured values provide the basis for determining the carbonation level.

5. Automatic CO₂ Volume Calculation

After pressure and temperature measurements are obtained, the CLRT-01 can automatically calculate and display the corresponding CO₂ volume based on its embedded carbonation table.

This reduces manual calculation and helps simplify routine quality-control testing.

Manual Carbonation Testing with CLRT-02

Stránka CLRT-02 Manual Carbonation Tester for Beveragesuses the same basic pressure-temperature concept but places the operator in control of the testing process.

This makes it suitable for laboratories that do not require automated agitation and data processing.

The basic manual procedure consists of six steps:

  1. Pierce – Manually penetrate the bottle cap using the quenching piercing head.
  2. Release Pressure – Open the vent valve to release excess gas.
  3. Stabilize – Close the valve and allow the pressure to stabilize.
  4. Agitate – Shake the beverage manually for approximately 40 seconds.
  5. Measure – Record the stabilized pressure and beverage temperature.
  6. Calculate – Compare the pressure-temperature readings with the carbonation volume table.

The CLRT-02 uses a 0–1 MPa pressure gauge with 0.0001 MPa resolution and supports pressure units such as MPa, psi, and bar.

Its manual operating method makes the instrument particularly practical for R&D laboratories, QA laboratories, and smaller testing volumes where automation is not essential.

ASTM F1115 for Beverage Carbonation Testing

ASTM F1115 – Standard Test Method for Determining the CO₂ Loss of Beverage Containers is an important reference for carbonation-related testing of beverage containers.

When selecting a Carbonation Tester for Beverages for ASTM F1115-related applications, laboratories should consider not only the instrument’s pressure range but also the complete testing procedure, sample configuration, temperature conditions, pressure stabilization, and data interpretation.

Both CLRT-01 and CLRT-02 are designed to support carbonation testing applications associated with ASTM F1115.

The instruments can also be applied with GB/T 10792, the Chinese standard for carbonated beverages.

ASTM F1115Determination of CO₂ loss of beverage containers
GB/T 10792Carbonated beverage testing

The applicable edition and detailed test requirements should always be verified by the laboratory before conducting compliance testing.

Carbonation Testing in Beverages: What Affects the Result?

A reliable carbonation test depends on more than simply reading a pressure gauge. Several factors can influence the measured result.

Beverage Temperature

Temperature has a direct relationship with CO₂ solubility and pressure. Therefore, temperature should be measured accurately and considered when interpreting carbonation results.

The CLRT-01 provides real-time temperature monitoring with a 0.1°C resolution, helping operators monitor the sample condition during the test.

Agitation

Carbonated beverages may not have a completely uniform CO₂ distribution immediately after sampling. Agitation helps establish a more consistent condition before the final measurement.

The CLRT-01 uses controlled servo agitation, while the CLRT-02 relies on manual shaking.

Pressure Stabilization

Pressure should reach a stable condition before the final reading is recorded. Excessive pressure fluctuation can reduce measurement consistency.

The controlled pressure-release workflow of the CLRT-01 helps standardize this part of the procedure.

Operator Technique

Manual testing introduces additional variables, including:

The CLRT-02 is still suitable for routine laboratory work, but operators should follow a consistent procedure.

Which Carbonation Tester for Beverages Is Better for Your Laboratory?

Neither instrument is universally better. The appropriate choice depends on testing volume, workflow, operator requirements, and budget.

Choose CLRT-01 If You Need:

The CLRT-01 is particularly suitable for beverage factories, centralized QA laboratories, R&D centers, and applications where multiple samples need to be tested under consistent operating conditions.

Choose CLRT-02 If You Need:

The CLRT-02 can be a good choice when the laboratory already has an established manual procedure and does not require automated agitation or automatic result processing.
