Note 1!
Not all data listed are applicable to all analyzer versions (e.g. 60 °C [140 °F] thermostatically
controlled box is not available for electrochemical and trace oxygen, nor for
Note 2!
For NDIR/UV/VIS measurements, take into account that
• sample gas may diffuse or be released by leakages into the analyzer enclosure
• if existent in the analyzer surroundings, the component to be measured may enter the enclosure.
Concentrations then may increase inside the enclosure. High concentrations of the component
to be measured inside the enclosure may influence the measurement by unintended absorption,
which could cause drift of the measurement.
A remedy for this issue is to purge the housing with gas not containing the component of interest.
