Haffmans Portable Optical CO2 /O2 /TPO Meter - c-DGM

Main Content Starts Here

PORTABLE AND VERSATILE MEASUREMENT

The Haffmans CO₂/O₂ Gehaltemeter, type c-DGM, is a multifunctional device designed to measure:

  • Dissolved CO₂ and dissolved O₂ in liquids
  • O₂ content in gases
  • CO₂ purity in gases
  • Total Package Oxygen (TPO) in beverage containers

Its robust and portable design makes it ideal for use both in the laboratory and directly in the production environment.

Key advantages:

  • Suitable for both the brewing and soft drink industries, thanks to its ability to handle high product pressures
  • Reproducible results ensure consistent accuracy
  • Capable of measuring CO₂ gas purity with precision

HOW IT WORKS

When a CO₂ measurement is initiated, the O₂ content is automatically recorded. The device then establishes equilibrium, followed by the measurement of pressure and temperature. Based on these parameters, the dissolved CO₂ content is calculated and displayed. All data can be securely transferred to a PC via the included interface cable.

 

In addition to combined CO₂/O₂ measurements, the c-DGM also supports:

  • Single O₂ measurements
  • Continuous O₂ monitoring
  • Single CO₂ measurements

Furthermore, the device calculates the Total Package Oxygen (TPO) value using the Uhlig method, available in both the CO₂/TPO combined mode and the single TPO measurement mode.

FIELDS OF APPLICATION

Versatile Use – At-Line and Laboratory Measurement
The portable C-DGM is designed for flexible CO₂ measurement, whether directly in the production environment or the lab.

  • At-line: Take measurements directly from process lines, vessels, tanks, or kegs—right where production happens.
  • Laboratory: Analyze samples from bottles or cans with precision, ensuring consistent quality across your beverage range.
