Description

LANGRY Penetration Concrete Strength Tester SJY-1000B is suitable for masonry concrete strength tests. The penetration method is based on the correlation between the penetration depth of the nail into the concrete and the compressive strength of the concrete, using the lever force method, compressing the working spring to load, storing potential energy, and instantaneously penetrating the measuring nail into the concrete. A field detection method that converts the intensity by combining the penetration depth with the relevant intensity measurement curve.
