Digital Multi-functional Electric Portable Compactor, heavy and light compactness, two specimen cylinder diameter, ABS plastic - details see: https://www.machineto.com/digital-multi-functional-electric-portable-compactor-10106446

STDJ-3A Digital Multi-functional Electric Portable Compactor (hammer in center)

1. Application:

• This machine is used to test the relation between water content and dry density of soil by certain compaction power with standard compacttion method, to determin the soil's best water content and related max. dry density, so as to understand the soil's compactability as the basis of caly subgrade compactness control in construction site.
• The machine is suitable for clay subgrade filling construction design in pavement, railway, water consevancy and construction.
• It is a mechantronics apparatus, it's structure performance is in accordance with the compactness testing specimen production requirement for CRB testing and rebound modulus testing completely.

2. Characteristic:

• Microcomputer control
