This is a lightweight, freeze-resistant sampler for collection of suspended-sediment samples where wading-rod suspension is used. It was designed for use in sub-freezing winter conditions and use under ice cover.

The open sheet-metal body of this sampler provides easier removal of the sampler container when ice forms over the sampler as it leaves the stream. The low mass of the sampler also defrosts more rapidly than the US DH-48.

The sampler consists of a streamlined plated steel frame. The sampler weighs 4 pounds (1.8 kgs) including the sample container (sold separately). An intake nozzle extends horizontally from the nose of the sampler body. A standard 1/2" wading rod is threaded into the top of the sampler body for suspending the sampler. The sample container is held in place and sealed against a rubber gasket in the sampler head, by a rubber cord at the rear of the sampler. The instrument can sample to within 3 1/2 inches (9 cm) of the stream bed. The sampler is calibrated and supplied with two 1/4 inch nylon nozzles. The DH-75Q pop sampler is a modification of the DH-75 allowing it to tilt to a vertical position to permit use through a 6-inch ice hole to obtain a suspended-sediment sample.
