For non destructive strength testing of concrete and structural components .
In operation, the hammer hits the concrete at a defined energy.
Its rebound is dependent on the hardness of the concrete.
Through the use of the included conversion table ,
the rebound value can be converted to compressive strength.
The standard (Type N) hammers that displays rebound values on a mechanical sliding scale .
For testing thin walled structural components with a thickness of less than 10 cm or rock cores .
All models include rubbing stone , carrying case and instruction booklet with conversion charts.
