STANDARD: ASTM C803
This portable instrument is used to measure the resistance of
materials in situ for new or existing constructions. The operating
principle which the instrument is based is the capacity to nail a
pin into the surface of the material, since the penetration depth is
inversely proportional to compressive strength is easy to determine
the material resistence. The unit measures compression strength
of concrete and mortar in situ with accuracy and speed. It is a safe
tool that uses a mechanism equipped with a calibrated spring to
insert a steel nail into the material to be investigated. The depth
of penetration of the nail is measured and correlated with specific
curves to the compression strength of the test material. The removable
small section nail facilitates the use of the instrument and the
correct execution of the test.
