RBMH-80 Rotary Bucket Sediment Sampler

The US RBMH-80 is a hand-operated sampler that has a semi-cylindrical bucket for collecting the bed material samples. Operation is simple: the lever on the handle opens and closes the bucket. The sampled material is protected from erosion while rising through the water column. It is constructed from lightweight aluminum and uses a BM-54 sample bucket.

The bucket size is 8 cm by 7 cm and collects a sample to a depth of 5 cm.
