Olson Instruments CTG-1T Concrete Thickness Gauge

You no longer need to drill, core or excavate to determine concrete slab thickness using our CTG™ gauges.

You can now verify the thickness of concrete flatwork in 1-Easy Step!

The CTG™ line of instruments are nondestructive, battery-powered handheld systems for measuring the thickness and integrity of concrete slabs, pavements, tunnel linings, walls and other plate-like structures. These systems feature a handheld gauge (shown at top left) that records thickness information, a handheld test head (shown at top right) for generating and receiving sound waves and a telescoping pole for use on flatwork or overhead. The CTG™ requires no special knowledge or training. It reliably measures the thickness of any type of concrete using the Impact Echo (IE) principle. Use it right out of the case with built-in default concrete parameters, or for greater accuracy, simply calibrate the CTG instrument by testing at a point of known concrete thickness as a calibration reference for the speed of sound in that concrete and start testing!

F E A T U RES:

  • Ruggedized handheld test head with integrated displacement transducer and solenoid impacter
  • No coupling agents required for use of test head
  • on concrete
  • Works on cured, hardened concrete in air or on grade
  • Easy to read LCD display for outdoors and
  • switchable backlight for indoors
  • Works through paint and most bonded tile...it even checks for bonded tile!
  • English (inches) or Metric (centimeters) thickness and spectral echo signal display
  • Easy velocity calibration at known thickness location
  • Download test time/data and results into your PC
  • Import thickness data table into popular spreadsheet programs
  • Save selected date/test time and spectral thicknesresults for reviewing at a later time
