Schmidt rebound hammers for concrete strength and rock testing

Schmidt rebound hammers

The original rebound test hammers for compressive strength and homogeneity assessment

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.

Description
Description

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

Description

The Schmidt OS-120 pendulum hammers are designed to test on softer material such as light weight concrete, gypsum boards, fresh concrete and the mortar of joints in brickwork. 

Description

The RockSchmidt is a variation of the SilverSchmidt adapted specifically for rock testing applications such as UCS correlations or to predict penetration rates for tunnel boring machines and rotary drum cutters. 

Description

The Original Schmidt OS8000 is the Original concrete test hammer, now digitally redefined - and it is also the most advanced R-value hammer ever made, with unmatched performance, ease of use, and versatility, as well as reporting on the go thanks to its mobile app.

Description

Silver Schmidt OS8200 is as accurate, reliable, and versatile as ever—and now, connected, thanks to its optical measurement technology delivering Q-value measurements, paired with digital productivity features and user-friendly mobile apps.
