PSS-20 portable gas conditioning systems is equipped with a pull ring Fig. 2/④ which can be
•
equipped with a strap to facilitate the user's portable movement.
When the heat exchanger tubing needs to be replaced, it is convenient to replace it by opening the
•
top of the case Fig. 2/⑤. The grilles on the left and right-side panels ensure adequate ventilation
and heat dissipation. The unused mounting holes are sealed with a blocking column.
Optional：Acid dosing package
Under ultra-low emission conditions, a portable flue gas analyzer is faced with a great challenge to
monitor the flue gas with high humidity, low temperature, low SO
how to effectively remove water vapor in the flue gas without affecting the accurate analysis of a low
SO concentration.

For ultra-low emission monitoring, PSS-20 specially introduces portable acid-added condensation
pretreatment, which can well solve the problem of SO2 soluble in water and can completely meet the
monitoring requirements of high humidity and low concentration SO2 and NOx under ultra-low
emission conditions.
It is recommended to add 5 % H
When adding acid, first turn on the acid dosing peristaltic pump switch Fig. 4/ ④.The peristaltic pump
will start conveying the acid. The acid will then enter the heat exchanger tubing together with the
sample gas through the PSS-20 add dosing Inlet Fig. 3/ ④. The excess acid will be discharged through
the SR25.2 peristaltic pump Fig. 3/ ③ with the condensate. When adding acid it is not needed to turn
off the switch of the acid dosing peristaltic pump switch Fig. 4/ ④.
