Non-destructive strength testing of concrete has a whole new look thanks to the new SilverSchmidt Test Hammer. The new SilverSchmidt redefines strength testing with the use of what is called a "Q" value as opposed to the classic use of an "R" value. What this means for you is that the new SilverSchmidt provides a more accurate method of measuring impact and rebound, which eliminates the need for referencing a chart, based on orientation, to determine the strength of concrete. The new SilverSchmidt calculates the test results for you and provides the concrete strength in any of the many user-defined measurement modes.
The Silver Schmidt provides an easy-to-use graphical, icon interface that provides the operator complete control of the test parameters and results display. Review of test data can be performed for the last 20 measurements.

The H-2975, Type N Hammer is designed for testing concrete items 4" (100mm) or more in thickness, or concrete with a maximum particle size less than or equal to 1.25" (32mm).It is designed for testing concrete within a compressive strength range of 1,450 to 10,150 psi (10 to 70 N/mm[sup]2[/sup]) and Impact energy of the test is 1.6 ft-lbs (2.207 Nm) The standard (Type N) hammer displays rebound values on a mechanical sliding scale. These values can then be correlated to compressive strength by using the conversion table chart affixed to the hammer.
Type N Schmidt Hammer— H-2975
$675.00 Add to Order
Same as above, but includes a conversion table with a N/mm[sup]2[/sup] scale instead of psi.

The Digi-Schmidt Concrete Test Hammer couples the original Schmidt Hammer with rebound measuring sensors and microprocessor technology to provide an instrument designed applications requiring numerous measurements. The method is rapid, reproducible, and has resolution previously unattainable by manual models.
The hammer is connected to a control and display unit by means of a connecting cable. Strength values are shown digitally as they are taken and also displayed as groups of bars on the 128 x 128 pixel graphic LCD. Mean value and standard deviation for a preset number of measurements are computed and displayed. Via a menu display, the user can select hammer impact direction (up, down, horizontal, etc.) and desired engineering units (psi, MPa, kg/cm[sup]2[/sup], or N/mm[sup]2[/sup]) and indicates the specimen size and type (cylinders, cubes, etc.) for which strength data are to be predicted.
Instrument measuring range is 1,450 to 10,150 psi (10-70 N/mm[sup]2[/sup]) using 2.207 Nm impact energy. Accuracy is ±0.2R with 0.5R reproducibility. Rebound vs. strength correlation curves for 7 and 28 day strengths are installed in memory, or the users own data may be installed via keyboard entry. The Internal memory holds 5000 measurements, each with date and time. Data can be transferred via the RS-232C interface to a PC in Microsoft Excel using the included cable and software. Direct printing is possible.
The Digi-Schmidt consists of the test hammer, control and display unit, connecting cable, PC cable, carrying strap, rubbing stone, instruction manual and a plastic carrying case. Meets ASTM C805.
