CO2 measure advance launched

Haffmans CO2-Selector: other gases do not effect results

Laser allows non-invasive filled measurement

Pentair Haffmans has launched a breakthrough in CO2 measurement, a non-invasive solution for filled containers.

The Haffmans CO2-Selector offers a key advantage over conventional technologies - piercing of the container is not required to undertake measurements, thus eliminating all product loss. 

The instrument measures the headspace CO2 content and internal pressure, and accurately the dissolved CO2 content in the package. This is accomplished by use of a high-precision laser technology. 

Here’s how it works: the instrument’s laser transmitter sends a beam through the headspace of the package to a receiver. At a particular frequency, 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 CO2 concentration in the package is determined. 

Other gases present in the headspace, such as oxygen, nitrogen and hydrogen, do not have an effect on the measured results. In addition, the measurement is independent of the bottle’s colour or material. 

Pentair Haffmans is headquartered in Venlo, the Netherlands with a presence in more than 150 countries worldwide. It develops and supplies quality control equipment, microfilters and carbon dioxide systems for the brewing, wine, soft drink, bioethanol and biogas industries.
