Spring penetrometer

Reference: HR559
Standards: ASTM C803

It consists of a spring that inserts a steel dowel into the surface of the material. The spring is loaded by tightening the retraction nut until the activation mechanism closes, locking the spring in place. With the spring loaded, it is held 20 mm from the test surface. When the trigger is pulled, sufficient force is applied to test the compressive strength of the concrete or mortar up to a maximum of 37 MPa.
