The Haffmans Portable Optical O2/TPO Meter o-DGM combines high accuracy with excellent measurement stability. This optical O2 measurement technology is greatly improved compared to the traditional O2 measuring instruments. Frequent calibration of the O2 measurement is not required.
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 mea-
surement 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
and TPO measurement, based on the Uhlig method, from
a package.
The data can be securely transferred to a PC by using the
interface cable. Data analysis can be done via Pentair
Haffmans Navigator software.
