Federal Interagency Sedimentation Project (FISP) specialized samplers distributed by Geotech Environmental Equipment, Inc.
US DH-81
The US DH-81 handheld suspended sediment sampler developed by the Federal Interagency Sedimentation Project (FISP) is specifically designed to collect flow-weighted, depth-integrated water - sediments samples in wadeable streams and rivers. The systems central component is the US DH-81A Adapter, which attaches to a wading rod and supports a variety of caps, nozzles, and sample containers. The modularity allows for a flexible, configurable system that can be tailored to specific sampling environments. Call 1.800.833.7958 |
US D-95
The US D-95 is a depth-integrating sampler specifically engineered for collecting water-quality and suspended-sediment data in stream depths up to 15 feet. Designed for hand-line deployment, operated via a suspension system, such as a bridge board, crane, or reel. It’s built to meet the standards of the USGS National Field Manual, the US D-95 ensures scientific integrity and inflow efficiency across stream velocities ranging from 1.5 to 7.5 ft/sec.

US DH-95
The US DH-95 is a lightweight, hand-line suspended-sediment and water-quality sampler designed for versatile field deployment. Unlike its heavier counterpart (D-95), the DH-95 is light enough to be lowered and raised hand-over-hand using a flexible suspension line, yet robust enough for use in stream depths up to 15 feet. It fully complies with the protocols outlined in the USGS National Field Manual for the Collection of Water-Quality Data. Call 1.800.833.7958 |
