The Haffmans CO2-Selector provides an advanced solution for non-invasive CO2 measurement of beer in filled packaging. Using an innovative laser technology, it measures the partial CO2 pressure and total pressure of the headspace and accurately determines the dissolved CO2 content in the package. Piercing is not required to perform the measurement. The bottle is not damaged and no product is wasted.
How it works:
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, nitrogen, or hydrogen 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.
