Schmidt

The original and most comprehensive rebound hammer portfolio

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 first and most widely used instrument for non-destructive estimation of concrete strength properties, asphalt, mortar, rock and paper. Proceq rebound hammers are available in models with different impact energies, each designed for a specific test application. The SilverSchmidt is the latest generation of rebound hammer combining the ground breaking features of the OriginalSchmidt with the best of today’s technology. It is the first integrated rebound hammer featuring true rebound value and unmatched repeatability.

Description
Description

The SilverSchmidt is a unique integrated concrete test hammer featuring true rebound value calculated from the quotient of the impact velocity and rebound velocity to provide maximum accuracy. 

Description

The classic Original Schmidt hammer that became the basis of every major rebound hammer testing standard worldwide. Includes the NR and LR versions to record the rebound values directly on registration paper. 

Description

The DigiSchmidt is a digital version of the classic Original Schmidt with a display unit that allows the direct reading and display of the test results. 

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.
