US D-49 Sediment Silt Sampler

The head of the sampler is hinged to permit access to the sample container. Tail fins are provided to orient the instrument into the stream flow. The head of the sampler is drilled and tapped to receive the 6.3mm/4.8mm, or 3.2mm intake nozzle which projects into the current for collecting the sample. A port which points downstream is provided on the side of the sampler head from which air escapes as it is displaced by the sample being collected in the container.

Suspension equipment and sample containers are optional extras.

Q: What type of environments is this sediment sampler suitable for?

A: This instrument is ideal for freshwater environments such as rivers, streams, or other bodies of water requiring depth-integrated sediment load measurements, withstanding temperatures from -20C to 60C.

Q: When should I use a depth-integrating sampler like the D-49 model?

A: Deploy this sampler during water quality investigations that require a representative profile of suspended sediments across various depths, such as during environmental assessments or discharge monitoring studies.

Q: Where is the data collected by the D-49 sediment sampler stored?

A: Sediment samples are physically collected within the device, which has a sample data capacity of up to 5 liters. The samples are then removed for analysis after retrieval.

Q: What key benefits does the D-49 Sampler provide over powered alternatives?

A: The D-49 requires no external power, reducing operational complexity. Its rugged SS316 construction and manual operation make it reliable in remote field settings and ensure long-term durability.

Q: Can the D-49 Sampler measure in extreme weather conditions?

A: Yes, its design accommodates a broad temperature range from -20C to 60C, making it dependable in both cold and hot climates.

Q: What is included with the US D-49 Sediment Silt Sampler upon purchase?

A: The sampler includes necessary connectors and a user manual, providing the essentials for straightforward deployment and operation.
