Due to increased customer demand, Pentair Haffman has enhanced its Gehaltemeter: an oxygen (O2) detection system aimed at the beverage industry.

Pentair Haffmans’ portable oxygen (O2) Gehaltemeter, type o-DGM, and combined carbon dioxide (CO2) and O2 Gehaltemeter, type c-DGM, have been upgraded with the additional measurement value of Total Package Oxygen (TPO).

Designed for the beer and beverage industry, brewers can now use these instruments, in combination with an ISD-special sampling device, to determine the TPO content in filled packages, in addition to the dissolved O2 content. These improvements allow for flexible use for more comprehensive measurement results.

Pentair’s improved device continues to incorporate optical O2 measurement technology, which allows for reproducible and operator independent results, and is still supplied with a bumper to protect the instrument against physical impacts.


The Netherlands-based company provides breweries and beverage producers a complete range of technologies for measuring CO2 and O2 in laboratories, at-line and in-line. The company delivers products, services and solutions for its customers’ needs in water and other fluids, thermal management and equipment protection.
