The Windsor Pin System is a unique instrument for measuring the strength of new or existing construction materials in situ utilizing the established principle of resistance to penetration.
The Windsor Pin System measures the compressive strength of concrete, mortar and brick in-situ, quickly and accurately. A non-explosive instrument, the Windsor® Pin System uses a spring-loaded device to drive a steel pin into the concrete (or mortar). The depth of penetration of the needle correlates to the compressive strength of the material under test. A removable chuck and a small pin size facilitate the testing of mortar joints; this is the only system for testing the in-place strength of brick mortar joints.
