Stability
The following data only applies if all the influence variables (e.g.
flow, temperature and air pressure) are constant.
Linearity error
≤ 0.5 % of span
Repeatability
≤ 50 ppm O
2
(time base for gas exchange ≥ 5 min)
Zero drift
≤ 3 % of the span of the smallest measuring range (in
accordance with order) per week, at least 300 ppm O
2
per
week;
After longer transport/storage times, the drift can be higher
in the first weeks.
Span drift
• ≤ 0.1 vol.-% O
2
per week or ≤ 1 % of the measured value
per week (not cumulative), whichever value is smaller;
• ≤ 0.25 % of measured value per year, at least 0.05 vol.-%
O

per year
Output signal fluctuation (2 σ)
≤ 25 ppm O

Detection limit (4 σ)

Influences
Flow effect
≤ 0.1 vol.-% O
2
in the 30 to 90 l/h range
Associated gas effect
Information on the influence of associated gases can be
found in IEC 61207-3:2002 ‘Gas analyzers – Expression of
performance – Part 3: Paramagnetic oxygen analyzers’.
Temperature effect
Ambient temperature in permissible range.
• on the zero point:
≤ 1 % of the span per 10 °C, ≤ 2 % of the span per 10 °C in
combination with Uras26;
• on the sensitivity:
≤ 0.3 % of the measured value per 10 °C
Thermostat temperature = 64 °C
Air pressure effect
• on sensitivity without pressure correction:
≤ 1 % of the measured value per 1 % of air pressure
change
• On sensitivity with pressure correction using integrated
pressure sensor (option):
≤ 0.1 % of measured value per 1 % air pressure change;
for highly suppressed measuring ranges:
≤ 0.01 % of measured value per 1 % air pressure change or
≤ 0.002 vol. % O
2
per 1 % air pressure change, whichever
is greater.
Position effect
Zero-point shift ≤ 0.05 vol.% O
2
per 1° deviation from
horizontal location.
Position has no effect on the hard-mounted unit.
