The R800 Multi function Rebar Scanner and Corrosion detector is a high performance NDT instrument that is utilised to examine the active corrosion in rebar in buildings & structures and also provides the capability to detect location of rebar in concrete, measure rebar cover and estimate rebar diameter.
The R800 also provides Rebar Grid Scan Orientation and distribution of rebar.
The R800 rebar detection features are based on 2 probe options provided :
- A 4 wheel probe for scanning larger concrete stuctures and
- A small rebar detection probe for rebar detection in constricted or tight spaces
The R800 provides three methods of scanning for rebar :
General Scan : for fast detection of rebar.
Dense Rebar Measurement : for allowing detection of rebar in structures which may have presence of high density of rebars such as beams.
Grid Scan : that allows distribution of rebar to be evaluated through grid diagram with definition of rebar cover and diameter in X (Horizontal) and Y (Vertical) directions.
For measuring corrosion potential, the R800's corrosion detection features are based on a two electrode handle system which provides flexibility for the operator to:
- Test using one electrode based on half cell potential method.
- Test using two electrodes based on gradient method. In both cases, electrodes used are copper sulfate type.
The instrument is based on lithium ion rechargeable batteries for full day use.
