Concrete Test Hammer

quick overview :

• Concrete Test Hammer Manufacturer, Supplier and Exporter India

• 
  
• It consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar.
• A plunger is attached to the guide bar which is pressed against the surface to be tested.
• As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent (according to the strength of the surface) which is indicated by a rider on a calibrated scale.
• A lock button fixed on the body of the hammer locks the rider in place and the rider can be recurred to zero position by using the same button.
• The equivalent compressive strength can be computed from the chart supplied.
• Each hammer is calibrated against at standard test hammer, and is suitable for specimen of compressive strengths 100 - 700 kg/cm.
• The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case.
