An ultrasonic pulse velocity test is an in-situ, nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure or natural rock formation.
The main focus is on imaging solutions for non destructive testing of concrete structures, metal hardness testing, paper roll hardness testing and rock testing. Proceq is well known for patenting the Original Schmidt concrete test hammer as well as the Leeb rebound principle and is also the owner of the “Pundit” trademark for ultrasonic ...
The Rockwell hardness test is a hardness test based on indentation hardness of a material.

[1] There are different scales, denoted by a single letter, that use different loads or indenters.
