Haffmans Portable Optical O2 / TPO Meter o-DGM

Main Content Starts Here

Fast, accurate O2 measurement—anywhere in your brewery

The Haffmans O2 Gehaltementer, type o-DGM  is a portable, high-precision meter for measuring dissolved oxygen (DO) and Total Package Oxygen (TPO) in beer and other beverages.

Designed for brewers who need reliable, on-the-spot quality control, it uses optical O₂ technology for fast response times and stable readings—without the need for frequent calibration. 

BENEFITS

  • Portable and flexible: Use it at-line or in the lab—measure directly from tanks, kegs, bottles, or cans.
  • High accuracy: Optical sensor delivers precise results with minimal drift.
  • Low maintenance: No regular calibration required.
  • TPO measurement: Based on the Uhlig method for reliable package oxygen analysis.
  • CO₂ gas check: Also measures CO₂ gas purity, adding extra value.
  • Easy data handling: Export results to your PC via interface cable.

HOW IT WORKS

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 deaerated water).
  • Wide measuring range (WLO) for accurate DO measurement of beverages < 45 mg/l (e.g., wort, soft drinks, and non-deaerated water).

Three measurement modes are available:

  • Single sample
  • Continuous O2 measurement from the production process.
  • TPO measurement from a package.

The data can be securely transferred to a PC using the interface cable. 

FIELDS OF APPLICATION

  • At-line: Sample directly from process lines, vessels, or kegs during production.
  • In the lab: Analyze bottled or canned samples post-packaging.
