US D-99 Depth integrating suspended hand line sampler

HIF/FISP Part # 4101020

HIF only has one sampler and it is available for rent only).
 
The US D-99 is a collapsible-bag suspended-sediment/water-quality sampler capable of collecting a 6-liter sample. It is 39 in long, weighs 275 lbs, and has a hollow cavity inside the sampler body. It is fabricated from a bronze casting with a high-density polyethylene tail. It has a hinged head that closes horizontally and holds the nozzle holder and nozzle in place. All metal parts are plastic coated. The bag is attached to the nozzle holder with a hook-and-loop strap. The sampler uses a plastic or TFE nozzle and a plastic or PFA bag as the sample container. The US D-99 meets the protocol for water quality sampling as outlined in the USGS’s National Field Manual for the Collection of Water-Quality Data.

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:
