Concrete surface roughness tester Ra Rz Rq Rt
Applications: Widely used in construction site to measure surface roughness of concrete.
Principle: The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier.
