Haffmans Gehaltemeter – Portable, Optical CO2/O2/TPO Metering Systems

Haffmans Gehaltemeter c-DGM

The Haffmans Portable Optical CO2 /O2 /TPO Meter c-DGM combines the internationally accepted determination of the dissolved CO2 content based on Henry’s Law with a highly accurate dissolved O2 and TPO measurement. The Gehaltemeter enables a fast and accurate determination of the CO2, O2, or TPO content in beer and carbonated beverages. Contact us today.


  • Accurate product control
    – reproducible and operator independent results
  • Cost savings
    – lower investment costs (one device for CO2, O2, and TPO measurement)
    – less labor intensive
    – reduction of beer loss
    – low maintenance
  • Bumper delivered as a standard accessory for protection against physical impact in harsh environments.

Haffmans state-of-the-art optical CO2/O2/TPO measurement technology is greatly improved compared to the traditional CO2/O2/TPO measuring instruments and doesn’t require frequent calibration. Its design allows for higher product pressure, making it suitable for the soft drink industry. Up to 10 different product types can be programmed into the device. The optional bumper protects the c-DGM against physical impact in harsh environments.

The Haffmans Portable CO2/CO2/TPO Meter c-DGM enables:

  • Combined CO2 /O2 measurement
  • Single CO2 measurement
  • Continuous O2 measurement
  • Single O2 measurement
  • Combined CO2 /TPO measurement
  • Single TPO measurement
  •  At-line sampled directly during the production process (from process lines, vessels, tanks, or kegs)
  • Laboratory, after the production, sampled from a variety of bottles or cans


I-DGM – Meter for dissolved CO2 only

O-DGM – Meter for dissolved O2 & TPO

  • The o-DGM is available in two measuring ranges:
    – low measuring range (LHO) for accurate DO measurement of beverages < 2,000 ppb (e.g. beer and aerated water)
    – wide measuring range (WLO) for accurate DO measurement of beverages < 45 mg/l (e.g. wort, soft drinks and non-deaerated water)
