STANDARDS: EN 12504-2, 13791; ASTM C 805; BS 1881:202
The Concrete Test Hammers are the most widely used portable NDT measuring instruments for a rapid assessment of the condition of a concrete structure.
The classic Original Schmidt Hammer that became the basis of every major rebound hammer testing standard worldwide. Includes the NR and LR versions to record the rebound values directly on registration paper.
Type N/L: The benchmark against which all rebound hammers are compared and the basis of every international rebound hammer standard. Available with diﬀerent impact energies allowing customers to test a wide variety of materials and types of structure.
Type NR/LR: Ever popular version with impact values recorded as a bar chart on registration paper for ease of control. Greatly simpliﬁes the calculation of the rebound value and in checking the uniformity of the object under test. One roll of paper can record up to 4’000 impacts.
Original Schmidt Hammers are supplied with Impact Device, Carrying Case, Grinding Stone, Operating Instructions and Calibration Certiﬁcate.
Type NR and LR additionally with 3 rolls of registration paper.
The SilverSchmidt is a unique integrated concrete test hammer featuring true rebound value calculated from the quotient of the impact velocity and rebound velocity to provide maximum accuracy.
ST: Standard model. Hammerlink software provided for performing ﬁrmware upgrades and selecting statistics presets only. Useful memory limited to the last 20 series.
PC: Full Hammerlink software functionality. Extended memory usage. Download to PC. User deﬁned custom curves.
Type N: Standard impact energy. Test object should have minimum thickness of 100 mm (3.9”) and be ﬁrmly ﬁxed in the structure.
Type L: Low impact energy. Suitable for brittle objects or structures less than 100 mm (3.9”) thick.
Intuitive User Interface
The language independent user interface is simple to use and provides all of the functionality necessary for a rapid assessment of the structure. Practically every command can be activated either directly or in two consecutive steps.
Data Acquisition and Processing
Pre-programmed statistical methods in accordance with all of the major standards assures an error free, rapid determination of the rebound value.
