The concrete test (Schmidt) hammer is used to evaluate the surface hardness of hardened concrete in order to evaluate the strength in various parts of the structure.
CONTROLS model (we keep them in stock): G-C0181/C: Concrete test hammer type N. Aluminium body. Conforming to EN 12504-2 and ASTM C805. Hard plastic carrying case and calibration included. Also known as a Schmidt Hammer or Concrete Rebound Hammer, the hammer may be used for comparative testing, referenced against a concrete with known strength or against a concrete verified as conforming to a particular strength class. The rebound hammers measure the rebound of an anvil impacting a plunger in contact with the concrete surface. 58-C0184: Calibration anvil used for the periodical calibration of the concrete test hammer 58-C0181/C and 58-C0181/DGT. Made from special alloy steel.

Digital rebound test (Schmidt) hammer CONTROLS model:
58-C0181/DGT: User programmable digital concrete hammer. 110-230V, 50-60Hz, 1Ph Provided complete with: multi-voltage / multi-frequency battery charger and suitable cable; USB cable for PC connection; PC software; abrasive stone; user manual and carrying case. The rebound number determined by this method can be used to assess the uniformity of concrete in situ, to delineate zones or areas of poor quality or deteriorated concrete in structures. This NDT test method is not intended as an alternative for the compressive strength determination of concrete, but with suitable correlations already saved in the instrument, it provides an estimate of the in situ compressive strength. With this advanced instrument the rebound value is calculated with an innovative technology taking into account the anvil speed before and after the impact. This new working principle is equivalent to the traditional measurement of maximum spring length after the impact, but it provides the following benefits:

A Pull-Off tester is mainly used to evaluate the bond strength of two layers of concrete or the adhesive strength of surface coatings (e.g. cement plaster, lime, wall plaster etc.) on its support.
CONTROLS model: 58-C0215: Pull-Off/Bond strength digital tester. 16 kN cap. Battery operated. Complete with AC adapter. 110-240V, 50-60 Hz, 1F The apparatus is basically a dynamometer fitted with a load cell and high resolution digital display unit. The direct tensile force ia applied by rotating the hand wheel. The 16 kN capacity and the high resolution assure a wide working range ideal for a vast number of materials and applications. It is supplied complete with: aluminium test discs 20 and 50 mm dia., screw bolt, traceable calibration certificate and carrying case. A wide range of accessories, such as adhesive compound, disks with various shape and dimensions, drill bits are also available. |

Automatic motorized Pull-Off bond strength tester
58-C0215/AUTO: Automatic motorized Pull-Off / Bond strength tester. 16 kN cap. Battery operated. Complete with AC adapter. 110-240V, 50-60 Hz, 1ph It is fitted with a high resolution load cell and houses a built-in motorized hydraulic actuator automatically controlled by the advanced electronics and closed loop algorithms. The 16 kN loading capacity, the high resolution load cell and the great stability of the electronics, assure a wide working range ideal for a vast number of materials and applications. The ultra-compact shape and the lightweight feature make this instrument particularly suitable not only for laboratory use but also for uneasy on site applications such as large walls and ceilings. It is supplied complete with: aluminium test discs 20 and 50 mm dia., screw bolt, traceable calibration certificate and carrying case. A wide range of accessories, such as adhesive compound, disks with various shape and dimensions, drill bits are also available.
