HAFFMANS SELECTOR: NON-INVASIVE CO2 MEASUREMENT

The Haffmans CO₂-Selector provides an advanced solution for non-invasive CO₂ measurement in the filled package. Using an innovative laser technology, the Haffmans CO₂-Selector measures the partial CO₂ pressure and total pressure of the headspace, and accurately determines the dissolved CO₂content in the package. Piercing is not required to perform the measurement. The bottle is not destructed and no product is lost.

The Haffmans CO₂-Selector’s laser transmitter sends a beam through the headspace of the package to a receiver. At a particular wavelength, the CO₂ molecules in the headspace absorb the infrared light of the laser. Based on the width of the absorption lines and the intensity, the total pressure and the partial CO₂ pressure in the package is determined. Other gases present in the headspace – such as oxygen (O₂), nitrogen (N₂) or hydrogen (H₂) – do not have an impact on the partial CO₂ pressure, enabling a CO₂ selective measurement. In addition, the measurement is independent of the color or material of the bottle.

Only a few minutes are required to prepare the package by shaking it to equilibrium and performing the measurement. The procedure is simple and repeatable, which allows for an unlimited number of CO₂ measurements to be conducted on the same package.
