Concrete Rebound Hammer (Sclerometer) NOVOTEST MSh

The concrete rebound hammer (sclerometer) tests the strength of concrete and other building materials by impacting a plunger on the surface and measuring the height of the rebound, which is proportional to the material’s strength and can be interpreted using supplied calibration charts.

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

There are several modifications of the measuring methods, which are different in impacting energy:

– Concrete Rebound Hammer NOVOTEST SH-225

– Concrete Rebound Hammer NOVOTEST SH-75

– Concrete Rebound Hammer NOVOTEST SH-20

Application:

Purpose: Designed to control and verify the accuracy of Rebound hammer readings, ensuring they meet the specified standards.
Test procedure: To determine the accuracy of the readings, conduct 5 to 10 measurements, calculate the average, and compare it with the reference value provided in the anvil’s manual, considering the acceptable margin of error.
