Search Heads for Elcometer 331 Series Concrete Cover Meters determine location, depth and placement of rebar and other metal materials encased in concrete. The Standard Search Head detects large bars at up to 3.75in (95mm) depth with ±3% accuracy. Smaller bars at shallower depths can be located to ±1mm. Narrow-Pitch and Deep Cover Search Heads are also available for better resolution or extended range. The Narrow Pitch Head can locate #3 (10mm) bars with as little as 2in (40mm) of separation. The Deep Cover Head accurately locates bars in up to 7in (180mm) of cover.
