US D-95 Depth integrating suspended hand line sampler

HIF/FISP Part # 4101015

The US D-95 suspended-sediment and water-quality sampler is a depth-integrating sampler designed for use in streams not exceeding 15 ft in depth. It meets the protocols for water quality sampling as outlined in the USGS’s National Field Manual for the Collection of Water-Quality Data. The sampler is lowered and raised by means of a suspension system such as a reel and crane or bridge board. The sampler is designed to sample at an acceptable inflow efficiency in stream velocities ranging from 1.5 to 7.5 ft/sec.

The sampler weighs 64 pounds and is 26 in long with the bottle, cap, and nozzle in place. The bronze body casting is coated with plastic and the tail section is constructed from plastic to help avoid metal contamination during water quality sampling. The sampler is designed to use a 1-liter Teflon or plastic bottle mated to the US D-95 CapTM or US D-77 sampler cap and nozzle. Plastic and TFE nozzles with 3/16-, 1/4-, and 5/16-in internal diameter are available. The unsampled zone using the US D-95 is 4.8 inches. The recommended sample volume to be collected with the US D-95 sampler is 800 ml.

Includes case, hanger bar, strap, and retainer. Nozzles, caps, bottles, and adapters are not supplied with the sampler and must be ordered separately. The unsampled zone, the distance between the center line of the nozzle and the streambed, is 4.8”. The recommended sample volume to be collected with the US D-95 sampler is 800 ml.

Includes sampler with case, hanger bar and O-ring.

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:
