Application：ZBL-R630A is used to test the location of rebar in concrete, the thickness of the protective
layer, and the diameter, orientation, and distribution of rebar by using an electromagnetic induction method.
It also can be used to test the distribution of magnetic and conductor such as cables and metal pipes in non-
magnetic medium and non-conducting medium
