Original Schmidt

Proceq invented the Original Schmidt, the worlds first and now most widely used test hammer for analyzing the compressive strength of concrete properties.

The Original Schmidt will hit the concrete at a defined energy whereas its rebound is dependent on the hardness of the concrete and is measured by the instrument. The Original Schmidt is available in models with different impact energies, each test hammer designed for a specific test application, in order to meet the needs of the customers to investigate a wide range of material types and sizes, such as bridge decks, thin walls, cast stone components or small components.

Various models with different impact energies to cover a wide range of applications
Proven durability and quality compared with low cost copies
Established Proceq Swiss Made accuracy and reliability

Impact Energy: 2.207 Nm (N), 0.735 Nm (L)
10 to 70 N/mm2 (1'450 to 10'152 psi)

  • The Original Schmidt is used for the non-destructive measurement of the concrete/mortar compressive strength characteristics
  • Control of uniform concrete quality
  • Detection of weak spots in the concrete
  • The type L/LR Original Schmidt operates with significant lower impact energy, making this test hammer the ideal option for testing thin walled items with a thickness between 50 to 100 mm (2 in. and 4 in.) or for analyzing small components.
  • It is suitable for examining cast stone components which are sensitive to impact. In rock mechanics, the type L/LR Original Schmidt is commonly used for the classification of rock cores and brittle rock
