Selecting a bar size
The dimensions of reinforcement bars are stored in the Covermeter and include the following four standard bar series: Metric, US Bar, ASTM/Canadian and Japanese. Due to this wide selection of bar sizing, the Elcometer 331 Covermeters can be utilised worldwide with accurate results. When taking measurements for high tensile steel or Grades 304, 316 and Duplex Stainless Steel details for the Bar Grade and Bar size can be manually input into the Covermeter, or the gauge can be used in autosizing mode.
Autosizing and Orthogonal size function
Autosizing automatically calculates an estimate for the size of the rebar and the depth of cover. If this figure differs greatly from your expected rebar size, or you do not know the expected rebar size, the Orthogonal size function provides an accurate measurement of bar size. The step by step directions on the Covermeter make the accurate sizing of bars quick and easy.
