Concrete Test Hammer

Original Schmidt® Test Hammer

 

Concrete Test Hammer Concrete test hammer uses indirect means of obtaining relative value for compressive strength of finished concrete. Spring-driven hammer is used for non-destructive quality testing of concrete and other building materials in any structure or prefabricated section. Determines when forms may be removed or load applied, damage done to a structure by freezing or fire. Impact energy is 1.6 ft-lbs. (2.207 Nm). Unit has 1450 to 10,150 psi (10 to 70 N/mm2) capacity range. Lightweight portable test instrument works on the rebound principle.

To operate, place impact plunger against test surface and apply pressure until plunger disappears; hammer will release. Scale pointer reading gives rebound value in percent of the forward movement of the hammer mass. Includes rubbing stone, plastic case, instruction booklet and calibration curves. Meets ASTM C805.

Digi-Schmidt® 2000

 

Digi-Schmidt 2000 By entering the depth of carbonation, the conversion of rebound value to the compressive strength is automatically compensated.

  • Non-destructive measurement of the concrete compressive strength and control of the uniform concrete quality (in-situ concrete and prefabricated structures)
  • Detecting weak spots
  • Data-Transfer to PC/printer

Concrete Testing with original DIGI-SCHMIDT 2000 Hammer, types ND and LD

The classic ORIGINAL-SCHMIDT concrete test hammer is equipped with a sensor which measures the rebound value of a test impact to a high resolution and repeatability. Basic settings and measured values are shown on the display unit. Operating is menu-guided in different languages. The DIGI-SCHMIDT 2000 is available in two versions:
  • Type ND (impact energy) 1.6 ft-lbs. ( 2.207 Nm) - suitable for use on concrete components of 4” (100 mm) thickness or more
  • Type LD (impact energy) 0.54 ft-lbs. (0.735 Nm) - suitable for use on concrete components of thickness less than 4” (100 mm) and on cast stone material
