1.5 Sample Systems
In addition to the standard features and options, Panametrics offers a full line of sample handling systems for a
variety of applications. If needed, Panametrics can design and build a sample conditioning system to meet unique
application requirements. Please contact Panametrics for details. Table 2 below lists some background gases that
can interfere with the oxygen sensor.

(1)Recommended maximum exposure 30 minutes, followed by flushing with ambient air for an equal period.
(2)Minimal effect on sensor performance, but produces signal interference of 1:2 ratio for ppm levels only (e.g.,
100 ppm NO

looks like 200 ppm O

).
