Calibration
Zero-point calibration
With oxygen-free process gas or substitute gas
End-point calibration
With process gas with a known oxygen concentration or a
substitute gas such as dried air
Single-point calibration
Zero-point calibration with any oxygen concentration, e.g.
with nitrogen (N
2
) or ambient air, processed through a cooler
or H
2
O absorber.
Pressure correction by means of pressure sensor is recom-
mended for single-point calibration with air.
Depending on the measurement task involved, the zero- and
end-points should be verified periodically.
Calibration of measurement ranges with suppressed zero-point
Highly suppressed measurement ranges (≥95–100 vol.-% O
2
)
should only be calibrated with test gases with concentrations
in the selected measurement range.
Materials in contact with the sample medium
Analyzer
Sample chamber (direct connection): stainless steel 1.4305
(SAE 303), glass, platinum, rhodium, epoxy resin; seals: FPM
(Fluorocarbon rubber), PEEK, FFKM
Gas connectors of the solenoid valve (option in model EL3020)
PVDF
Gas inlet conditions
The analyzer must not be used for measurement of ignitable
gas/air or gas/oxygen mixtures.
Temperature
The sample gas dew point should be at least 5 °C below the
temperature throughout the sample gas path. Otherwise a
sample gas cooler or condensate trap is required. Water
vapor content variations cause volume errors.
Inlet pressure
p
e
= 2–100 hPa
Lower pressures require a sample gas pump and higher
pressures require a pressure reducer.
Outlet pressure
Atmospheric pressure
Flow rate
30–90 l/h
Abrupt changes in gas flow rates should be avoided when
using highly suppressed measurement ranges.
Corrosive gases
Consultation with ABB Analytical is required if the sample gas
contains Cl
2
, HCl, HF or other corrosive components.
The AO2000-Magnos206 analyzer should be used if the
sample gas contains NH
3
.
Flammable gases
The analyzer is suitable for measuring flammable gases in
general purpose environment (see page 16).

tions
