The US D-99 sampler will collect acceptable flow-weighted samples in stream velocities ranging from 3.0 to 15 ft/sec. Extreme care should be practiced when deploying the sampler at stream velocities above 10 ft/sec. The US D-99 sampler is capable of sampling to a depth of 78 ft with a 5/16-in internal diameter nozzle, 120 ft with a 1/4-in internal diameter nozzle, and 220 ft with a 3/16-in internal diameter nozzle. The unsampled zone using the US D-99 is 9.5 in.
Includes sampler with case, 1 pkg (20) of 6-L plastic bags, 1 TFE 6-L bag, hangar bar and pin, 3 TFE nozzles (3/16, 1/4, 5/16) a TFE nozzle holder and bag retention straps (2 ea).
Where and how the sampler is deployed in the field is as important as the fundamental design of the sampler. Additional information about how to properly use this sampler can be found in the following references:
