ECTHA 1000 research and innovation:
The ECTHA1000 mechanical rebound hammer is the product of direct experimentation on different types of concrete. Used appropriately and following the correct procedures, this is a valuable instrument for testing and evaluating the quality of concrete, ensuring totally reliable results.
what the ECTHA 1000 concrete rebound hammer can be used for:
- for checking concrete uniformity in different parts of a structure following events such as fire, explosion, overloading, earthquake, etc.
- for evaluating, against calibration curves, the quality of existing and freshly cast concrete on site
- for evaluating variations in concrete quality within time frames generally stipulated by contract terms
ECTHA 1000 experimentation:
The exclusive use of reliable and meticulously selected components, decades of experience in the manufacturing of NDT instru¬ments, functional, innovative design and ongoing scientific research conducted by our NDT centre in close collaboration with the Marche Region Polytechnic University have enabled us to develop and create this new generation of instruments.
EUROSIT, a firmly established name in the civil engineering sector, manufacturing accessories for topography and measurement instruments for non-destructive testing, has established its own in-house NDT centre, to develop and improve instruments used for non-destructive testing in civil engineering.
As a result of the substantial technological advancements in recent years in concrete manufacture, the way in which data from non-destructive testing methods is evaluated has been the subject of critical reconsideration.
In this context, the SOUTHGEOSYSTEMS - NDT - division has decided to revise the tables used to interpret rebound hardness scales, significantly increasing the scope for analysing concretes to a range from a minimum resistance of 5 N/mm2 to values as high as 120 N/mm2, which are now achievable with the ingredients and mixes available today.
Our research has focused on modifying our existing N type test hammer, defining new, more reliable correlation curves and devis¬ing the new SonReb procedure.
We have plotted these new curves through the non-destructive (identifying the rebound hardness numbers and velocity of ultra-sound impulse propagation) and destructive (press crushing) testing of 50 cubic test pieces (200 mm per side) for 20 distinct classes of agglomerate, for a total of 1000 samples.
The ECTHA 1000 mechanical test hammer is the result of this direct experimentation on different types of concrete. Used appropriately and following the correct procedures, this is a valuable instrument for testing and evaluating the quality of concrete, ensuring totally reliable results.

SINT 01 TESTING ANVIL
As it is based on a spring mechanism, the ECTHA 1000 test hammer must be calibrated as, after prolonged use, the elastic properties of the springs may change. Additionally, cement dust generated by the impact infiltrates into the instrument and may alter its me-chanical properties. Built in compliance with stan¬dards for weight, dimensions and hardness, the SINT01 anvil is equipped with a handle for easy trans¬portation during on-site analysis.
Anvil testing does not guarantee that different ham-mers will produce identical results in different ranges of the rebound hardness scale.
