42/24-10 EN Rev. 9 Appendix 3: ZO23 Trace Oxygen Analyzer Module A-3-1
Appendix 3 ZO23 Trace Oxygen Analyzer Module
Safety Information
WARNING!
The analyzer module must not be used for measurement of ignitable gas/air
or gas/oxygen mixtures. The concentration of flammable gases in the sample
gas must not exceed 100 ppm.
The presence of corrosive gases and catalyst poisons, e.g. halogens,
sulfurous gases and heavy-metal dusts, results in faster aging and/or the
destruction of the measuring cell.
The ingress of liquids into the analyzer module can lead to serious damage
including the destruction of the measuring cell.
After disconnection of the power supply, the case of the measuring cell has
an excess temperature of approx. 95 °C, which decreases only slowly.
Intended Application The trace oxygen analyzer module ZO23 is intended for the continuous measure-
ment of the oxygen concentration in pure gases (N
2
, CO
2
, Ar).
Please refer to the “Information for the Installation and Sample Conditioning” (see
page A-3-4).
