PRECAUTION
Conditioning the gas flow before it reaches the
analyzer is always recommended.
We recommend <50
o
C, <95% RH (non-
condensing), and free of hydrocarbon, volatile
and/or corrosive compounds and particulate
matter.
Take care not to pressurize the sensor beyond
20 psig; besides the possibility of damage,
erroneous readings can result. Temporary
conditions of pressurization (or having the
instrument in a chamber with lower than
atmospheric pressure) is okay.
We recommend that you use a flow meter on
the inlet of the instrument.
It is recommended that the analyzer operate at
above 30
o
F.
The following gases may interfere with your
readings: NO
2
(nitrogen dioxide), NOx
(nitrogen oxides), NH3 (ammonia).
The following gases may have a negative
impact on sensor life: Halogens,
F2, Chlorine, HCL, HF, SO
2
, H2S, Freons,
CFCs; SiO
2
, Si, Platinum, Zn, Cd, Pb, Bi
