3.3 Water Trap Filter
The water trap filter is made of PTFE (Teflon
) membrane
with a 0.2 micron pore size to prevent water from being
sucked into the sensor manifold, which would cause
extensive damage to the monitor. It will also remove any
dust and other particles from entering the monitor and
prolong the operating life of the sensor.
To install the water trap filter, simply insert the water trap
into the front of the inlet probe.
Some gases such as Cl
2
, ClO
2
, PH
3
, NH
3
, and HCN could
react with filtered particles or water or be absorbed by the
water trap housing material. In these cases, the water trap
filter can be removed. If the filter is not used, extra care
should be taken not to draw liquids into the unit, and it may
be necessary to maintain the pump more frequently.
