Proceq Original
Swiss Schmidt Hammer

The classic Original Schmidt hammer that became the basis of every major rebound hammer testing standard worldwide.

Proceq Original Swiss Schmidt Hammer

The Original Schmidt was invented and introduced into the market by Proceq in the 1950s. Since that time it has become the world’s most widely used instrument for non-destructive estimation of concrete strength properties, standardized in every major region.

Not limited to concrete it is also used for rock, paper and mortar. Proceq rebound hammers are available in models with different impact energies, each designed for a specific test application.

The latest models are the Original Schmidt Live, a fully connected hammer operating on iOs and Android and now the new SilverSchmidt OS8200 combining the proven accuracy of SilverSchmidt with all of the time saving reporting advantages of the live environment.
