A concrete test hammer being launched by Proceq is designed to read accurately on any surface from any direction, without the need to refer to conversion curves to compensate for impact direction. That’s because the SilverSchmidt measures the true rebound coefficient — or “Q” value — and converts it to compressive strength. The optically acquired “Q” value is intrinsically angle independent. Traditional test hammers rely on the “R” value of the mechanical travel of the mallet on rebound, which is prone to friction and gravity error sources. The SilverSchmidt is controlled via a graphic user-interface featuring a single button and inclination sensing.
