click pictures to enlarge
This is a 41-pound (19 kg) electrically operated
sampler for collection of suspended sediment samples at any point
beneath the surface of a stream, or for taking a sample
continuously over a range of depth. The sampler is made of cast
aluminum and is 28 inches (71 cm) long. The sampler head is hinged
to provide access for a quart (0.95-liter) size sample container
or, with adapter, a pint (0.47 liter) size container.
An electrically actuated valve mechanism to start and stop the
sampling process is located in the sampler head. The valve has two
positions:
The
equalizing position for balancing the pressure in the container
with the hydrostatic pressure, and
The
sampling position. The compression chamber in the body of the
sampler permits operation to depths of 180 feet (55 meters). A
battery source of about 36 volts is required to oper- ate the
solenoid. More voltage is required if a long suspension cable is
used. Each sampler is shipped in a hinged, wooden box suitable
for storing and transporting and the sampler can be epoxy-coated
for water quality sampling.

Point-Integrated Samplers- US P-63
This is a 200 pound (91 kg) electrically operated sampler for
collection of suspended sediment samples at any point beneath the
surface of a river, or for taking a sample continuously over a
range of depth.
The sampler is made of cast bronze and is 34 inches (86 cm)
long, is streamlined and equipped with tailfins to orient it in
the stream. The design and operation are identical to the P-72
except it is larger in size.
The B-56 sounding reel can be used to suspend this sampler if
it has 0.125-inch (0.32 cm) cable, although the E-53 sounding reel
is generally recommended with the larger samplers. Operating
instructions and a hinged, wooden box are included.
