Descriptions
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.
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.
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.
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.
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.
