Verify Concrete Slab Thickness & Integrity
No Coring — No Drilling — No Excavating

Meets ASTM Standard C1383

Concrete Thickness Gauge, an Impact-Echo device. This hand-held instrument tests concrete slab thickness and integrity. The CTG-2 is an easy to use, battery-powered, device.

Requires no special knowledge or training – connect the CTG-2 to your laptop or tablet and start testing with WinCTG2 software. For greater accuracy, calibrate the unit at a location of known thickness to obtain the concrete velocity for that job.

Applications

  • Elevated Slabs (i.e. Bridge Decks, Parking Garages)
  • Slabs on Grade (i.e. Roads, Runways & Floors)
  • Walls & Precast Panels
  • Ceilings
  • Tunnel Linings & Concrete Pipe
  • Columns & Beams
  • Foundations (thicknesses up to 6 feet)

Features

  • Ruggedized, hand-held test head with integrated displacement transducer and solenoid impactor
  • No coupling agents required for use of test head on concrete
  • Works on cured, hardened concrete of an elevated deck or on grade
  • Works through paint, epoxy, and most types of bonded ceramic tile
  • Switch between English (inches) or Metric (millimeters) units with the click of a button
  • Easy velocity calibration at known thickness location, or use default parameters
  • Thickness data table can be imported into most spreadsheet programs
  • Save results for later review
