Original SCHMIDT Hammer Type N

Measuring range 10 to 70 N/mm2 compressive strength (below 25 N/mm2 type P is better suited). Impact energy = 2,207 Nm.

Rebound values are read from a dial.

Testing the compressive strength of a prefabricated concrete girder. Rebound values are recorded by an assistant who will calculate mean values and read compressive strength values from a conversion diagram.

​

• Concrete uniformity testing

• Concrete compressive strength estimation

• Concrete screening test to identify core locations

• Concrete compressive strength range 10-70 N/mm2 (1'450 to 10'152 psi)

• In-situ rock testing on massive rock
