Sprin penetrometer
HR559
ASTM C803
It consists of a spring inserting a steel plug through the surface of the material.
As the depth of penetration is inversely proportional to the compressive strength, the device offers a quick and safe way to determine the strength of the material on site.
The spring is loaded by tightening the retraction nut ntil the trigger mechanism closes to hold the spring in place. With the spring loaded, it is kept at a distance of 20 mm from the test surface. When the trigger is pulled, there is enough force to test the compressive strength of concrete or mortar up to a maximum of 37 MPa.
