IN TRO DUC TION
This device is designed for use in the
field and is a simplified water sampler.
The sample is collected in a removable
inner bottle which will overflow five
times to insure a representative sample.
Samples may be taken at a controlled
depth by using a calibrated line.
Attaching the two pound weight to the
bottom of the sampling device insures
rapid descent and minimizes the
amount of drift due to currents. More
weight should be attached to the
sampling device in strong currents.
It is necessary to maintain a position
directly over the Water Sampling
Bottle when lowering it so that it
remains in an upright position. This
permits the displacement of all of the
air in the sampler so that it will fill
completely.
It should be noted that the bubbles of
air displaced from the sampler will be
observed downstream.

Remove the
plastic
center plug
with inlet
tubing
attached.
Insert the
collecting bottle
(0688-DO),
with the cap
removed, into
the inner
chamber of the
cylinder.

Attach the two
pound weight
(1068) to the
bottom bridle
of the sampler
by the snap
clamp.
Replace the
plastic
center plug.
Make sure
the inlet
tubing is in
the
collecting
bottle.
Attach the
snap clamp
on the
calibrated
line to the
bridle on
top of the
sampler.
Quickly lower the water
sampler to the desired
depth and leave until full.
This can be determined
when the bubbles from the
displaced air in the sampler
cease to appear. This usually
takes 3 to 5 minutes.

The dissolved Oxygen Test is made with reagents furnished in the
LaMotte Dissolved Oxygen Kit, Model EDO, Code 7414.

1. Follow steps 1-8 in Part A.
2. Remove the collecting bottle from the inner chamber.
3. To the sample, add 8 drops of *Manganous Sulfate Solution (4167)
and 8 drops of *Alkaline Potassium Iodide Azide (7186).
4. Cap the bottle and gently mix by inverting.
5. Allow the collecting bottle to stand undisturbed until the precipitate
settles into the bottom half of the collecting bottle.6.
6. Use a l.0 g spoon (0697) to add one measure of Sulfamic Acid Powder
(6286). Cap the collecting bottle and mix until the precipitate is
completely dissolved.
C. TAK ING SOUND ING WITH THE GRAD U ATED LINE
The two pound weight can be used for taking soundings. Attach the
weight to the graduated line by the snap clamp and lower it into the water.
Measure the depth at which the sounding lead strikes the bottom. The
line is graduated in meters with every fifty meters marked by a plastic
band.
