10 The purge vessel can also be used with the openings capped. In this option, fill
the vessel with 1L of the water to be sampled. Place the purge head into the
vessel.
11 Alternately, place the SituProbe purge head into the water supply to sample.
NOTE: Minimum submersion depth is 5.5 inches (14 cm) and the maximum is
just below the top nut.The depth should be measured from the bottom
of the purge head towards the electrodes.
CAUTION
If the purge head is submerged in a depth greater than
recommended, water in the HAPSITE may result.
