Scope of delivery
The Elcometer 331 Series (BH, SH, TH, THD) combines concrete cover measurement, rebar detection and half-cell measurement in a single high-performance tester. It enables the precise analysis of rebar location, concrete cover and corrosion risk in concrete structures and is ideal for inspection, maintenance and structural diagnostics.
System & Application
The instruments combine several testing methods in a single system: location and alignment of reinforcing steel, measurement of concrete cover, and assessment of corrosion potential using half-cell measurement. Graphical display and evaluation functions allow critical areas to be quickly identified and documented. :contentReference[oaicite:0]{index=0}
