WATER SAMPLER
MODEL JT-1 • CODE 1077
INTRODUCTION
The LaMotte Water Sampler is designed to take a 1.0 liter sample in water
with a depth of 5 meters or more. It is attached to a calibrated line which
is used to measure the depth at which samples are obtained. The line is
marked at 0.5 meter and 1 meter increments. A horizontal triggering
device is activated by a brass messenger which is sent down the line to trip
the closing mechanism and release the two fitted plungers. These plungers
provide a positive seal and prevent the sample from mixing with
intermediate layers of water as the sample is brought to the surface. A lead
collar has been added to the water sampler to insure rapid descent and to
minimize drifting due to current movements. The materials which were
chosen to make the sampler were selected for their ability to prevent any
contamination of the sampled water. Attached to the sampling chamber is
a special drain outlet for removing sample aliquots. All components of the
LaMotte Water Sampler are made with non-corrosive materials.
