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.
