เครื่องทดสอบกำลังอัดคอนกรีต Concrete Rebound Schmidt Hammer NOVOTEST SH

เครื่องทดสอบกำลังอัดคอนกรีต 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.

เครื่องทดสอบกำลังอัดคอนกรีต Concrete rebound Schmidt hammer (sclerometer) – is a device for concrete and other building materials strength testing. 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 is based on the impacting the impact plunger on the concrete surface with predetermined (normed) impacting energy and subsequent measuring of 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 with the calibration charts that are 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.
