Manual soil rammers, or compaction hammers, are used to compact soil samples for moisture-density relationship (Proctor) testing. These models are all constructed from rust-resistant plated steel and have a 2in (51mm) circular face. Newer U.S. Army Corps of Engineers specifications now require use of ASTM-style soil compaction hammers. Inquire for old-style USACE compaction hammers.
