Rebar locator (cover meter) survey
REBAR LOCATOR (COVER METER) SURVEY
Rebar locators or cover meters are offered in a wide range of degree capabilities starting from basic cover meters which are used to locate and measure rebar depth to comprehensive rebar scanners with 2D and 3D maps of rebar present in the concrete. The main task of the rebar detector is to measure the concrete thickness depending on the rebar diameter with an accuracy of up to 170 mm.
Uses of Rebar Locator
Rebar locators are designed to locate or scan the rebar content in the concrete. This test is helpful for the concrete cover determination, measures the rebar size, identifies the depth; calculates the rebar diameter and corrosion the occurs in concrete before drilling and before the core test. This test also helps in finding the physical condition of various structures, buildings, highways, roads, and other concrete structures.
Few of the advanced Rebar locators have a special mode that helps users to scan the object for the detection of rebar presence, its measure, and locating its position. This also provides an audible signal for rebar presence and helps in eliminating the need for constant display monitoring of the device.
Rebar Locator Survey Testing Reasons
This test is used to determine the surface hardness measurement of the concrete regarding soundness and quality. The low measurement numbers give weak concrete surface details which might be affected by corrosion and the high rebound number proves the high concrete quality.
