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

Manufacturing License for China Industrial Products(XK07-003-00014)

CE certified , conforms with ISO 9001 standard

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
• Base plate can be pulled and pushed automatically
• Strile one hammer in the center
• Can produce two kinds of spodosol and small stone specimen for 152mm and 100mm
• Have light compactness and heavy compactness
• Count, stop and cycle work automatically in operation
• Reliable result, convenient operation, hammer mark disreibute evenly, good quality specimen. It is suitable for onsite soil test in laboratory.
