Product Details

Concrete rebound Schmidt hammer (sclerometer) – is a device for strength testing of concrete and other building materials. The most common in the world instrument for measuring the strength of concrete is the Schmidt Hammer. The device is called by the name of the engineer Ernst Schmidt, who invented the construction of the sclerometer.
The method of strength testing of concrete with using the Schmidt hammer is based on the impacting the striker on the concrete surface with predetermined (normed) impacting energy and after measuring the height of the striker rebounding. The height of the striker rebounding will be proportional to the strength of concrete. The strength of concrete is determined by the calibration charts which is supplied with the instrument.

Concrete Rebound Schmidt Hammer NOVOTEST SH is very ease in operation, has good reliability of design and high measurement accuracy, so that this method is the most common method of measuring the strength of concrete in the world. The strength testing with the Schmidt hammer is correspond with ASTM C 805; ASTM D 5873 (for rock); DIN 1048, p. 2; ENV 206; EN 12 504-2; ISO / DIS 8045.

There are several versions of the measuring methods, which are different in impacting energy.

The most “powerful” Schmidt hammer is designed to measure the strength of concrete with a thickness of 70-100mm and more, also for the strength testing of massive rocks with impact energy – 2,207J (Nm). This is the base and the most common model of Schmidt hammer, about 90% of the Schmidt hammers in the world have the same impact energy.
Average “powerful” Schmidt hammer has the 735J (735 Nm) impacting energy. The impact energy is reduced threefold in compared with the base model. The main application of this instrument is measuring the strength of bricks and concrete products with a wall thickness less than 100 mm and small sizes of sample, also it used for testing the less strength stones and rocks.
The least “powerful” Schmidt hammer has 196J (196Nm) impact energy. The main purpose is the strength testing the mortar of brick masonry.

Depending on requerments tasks user always need to select the correct model of Schmidt hammer. All models, independently of impact energy, are devices for non-destructive testing, so that they are not destroying the object of testing.

To verify the accuracy of Schmidt hammer, is used a special calibrated anvil. Correctly functioning instrument have to display the certain value when it testing the standard anvil.
Advantages

Concrete Rebound Schmidt Hammer NOVOTEST SH has 3 modifications with different impacting energy, so that user can test all kinds of concrete and other building materials.
