• The compactor can be used with HMA-110 & HMA-111 4in(102mm) ID Molds, 5.5lb(2.5kg) weight with 12in(305mm) drop. The HM-530 also accommodates HMA-116 & HMA-117 6in(152mm) ID.
• Molds using either the standard 5.5lb(2.5kg) weight with 12in(305mm) drop or the modified 10lb(4.5kg) weight with 18in(457mm) drop. 
• The standard 2in(51mm) hammer can be replaced by one of the same 3.14in² areas, but with a pie-shaped face to cover the entire sample surface with 6in molds. 
• The hammer lift compensates the hammer drop for soil thickness in themold during compaction. 
• The free-fall hammer adjusts easily from 5.5, 10lb by the addition of a surcharge weight HM-530 mechanical soil compactor includes a 2in(51mm) round, 5.5lb (2.5kg) hammer, a 10lb pie-faced hammer for use with 6in molds, and a surcharge weight to increase total hammer weight to 10lbs(4.5kg). 4in(102mm) and 6in(152mm) standard compaction molds and a digital automatic counter with start/stop switching are also included. 
• Electronic safety interlock automatically shuts down operation if the door is opened HM-531 mechanical soil compactor for california method 216 is similar to HM-530, but is supplied with 2in(51mm) round 10lb hammer, required piston, and rod.
