Silver Schmidt Hammer

The Proceq Silver Schmidt Test Hammer has been redesigned to provide unmatched accuracy, repeatability and easy, intuitive operation. The Silver Schmidt features quicker and more accurate testing while addressing the previous insufficiencies of the traditional hammers. With the Silver Schmidt impact direction no longer has an impact on values; values are not affected by internal friction of the hammer operation, and, loss of accuracy because of seal problems is not affected.

In use, the Silver Schmidt eliminates cocking the hammer for each blow and recording the results, the Silver Schmidt allows you to do all your test blows in rapid succession, while it records the results. These results can then be reviewed. Intuitive User Interface is language independent through the use of easy-to-understand icons. The interface menu structure is similar to a mobile phones. Practically every command can be activated either directly or via no more than 2 consecutive steps.

All data is automatically saved and may be reviewed via the data list. The memory capacity is dependent of the length of tests in a series, but roughly 400 series with 10 readings each can be accomplished with the Silver Schmidt. The SilverSchmidt hammer includes these standard accessories: battery charger with USB cable, data carrier with software, carrying strap, grinding stone, chalk, documentation and carrying bag. Software provided for performing firmware upgrades and selecting presets only. Ship wt. 5lb. (2.3kg)

SilverSchmidt Hammer with Hammerlink Software

Same as H-2971STN, but includes complete Hammerlink software.
Hammerlink software features include: extended memory usage; rapid uniformity assessment with summary view; sorting of data; user-defined conversion curves (polynomial and exponential); User-defined statistical methods; Highlighting of mean, median and outliers; Carbonation correction; Print outs, and export to third party software. Ship wt. 5lb. (2.3kg).

Schmidt Hammer, Type N

The Original Schmidt® Hammer, Type N, is designed for non-destructive testing of 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 10,152 psi (10 to 70 N/mm²) and impact energy of the test is 1.6 ft-lbs (2.207 Nm). The (Type N) Schmidt hammer is pressed against the concrete structure and the rebound values are displayed on a mechanical sliding scale. These values can then be correlated to compressive strength by using the conversion table chart affixed to the hammer. The Original Schmidt Hammer is known for its durability and accuracy. Ship wt. 5lb. (2.3kg).

Schmidt Hammer, Type N (N/mm²)

The Original Schmidt Hammer, Type N with a N/mm² scale instead of psi. Ship wt. 5lb. (2.3kg).

Schmidt Hammer, Type NR

The H-2975NR hammer utilizes the same hammer mechanism as the H-2975, but includes an integral paper strip recorder, which provides rebound values as a bar chart on a paper strip, providing a hardcopy record of the test data. One roll of paper can document 4,000 test impacts. Shipping wt. 8 lb. (3.6kg).

Schmidt Hammer, Type L

The H-2975L hammer is designed for testing thin-walled structural components with a thickness of less than 4" (100mm) or rock cores. This hammer features an impact of 0.74 Nm, 1/3 less energy than the Type N hammers. Includes a conversion table with a (N/mm²) scale. Shipping wt. 5 lb. (2.3kg).

Digi-Schmidt Concrete Test Hammer

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 the menu display, the user can select: hammer impact direction (up, down, horizontal, etc.); desired engineering units (psi, MPa, kg/cm², or N/mm²), and indicate the specimen size and type (cylinders, cubes, etc.) for the strength data to be predicted.

The Instrument measuring range is 1,450 to 10,150 psi (10-70 N/mm²) 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. Shipping wt. 12lb. (5.4kg).

Replacement Paper for NR Hammer

Five-pack of chart paper used with the Type NR Schmidt Hammers.

Calibration Anvil

Calibration anvil ensures continued test accuracy. For use with all test hammers. Hammers should be periodically checked to determine correct performance. Shipping wt. 40 lbs. (18.1kg).
