Product FlyerVerify Concrete Slab Thickness & Integrity
No Coring — No Drilling — No Excavating
The Concrete Thickness Gauge (CTG-2) is a hand-held, battery powered, nondestructive system for measuring the thickness and integrity of concrete slabs, pavements, tunnel linings, walls and other plate-like structures using the IMPACT ECHO principle.
Requires no special knowledge or training — connect the Concrete Thickness Gauge to your laptop or tablet* and start testing with Olson's WinCTG2 software. For greater accuracy, simply calibrate the CTG-2 by testing a point of known concrete thickness to obtain the concrete velocity for that job.
NOTE: Impact Echo testing is available as an add-on for the Freedom Data PC and the NDE 360 platforms.

Key Features
| Ruggedized, hand-held test head with integrated displacement transducer and solenoid impactor | Switch between English (inches) or Metric (millimeters) units with a touch of a button |
| No coupling agents required for use of Impact Echo test head on concrete | Easy velocity calibration at known thickness location, or use Olson's default parameters |
| Works on cured, hardened concrete in air or on grade | Thickness data table can be imported into popular spreadsheet programs |
| Works through paint and most types of bonded ceramic tile | Save results for later review |
Specifications
| Thickness Range: 3.2" to 20" (81 mm) with built-in solenoid, to 6' (1.8m) when using a hammer. | Data Collection: works with most Windows 7+ devices |
| Accuracy: ± 2% when calibrated on a known thickness location | Frequency Resolution: 10Hz |
| Software Features: Olson's WinCTG2 Software is used for data acquisition and analysis |
Number of Samples Acquired/test: 4,545 Sampling Rate: 45,454 samples/second Max.Nyquest Sampling Frequency: 22,700 Hz |
| Report Capability: use X and Y coordinates to set up a test grid. Generate a thickness summary table which can be exported to most spreadsheets in comma separated format | Weight: 5 lbs (2.27 kg) combined weight of test head, batteries, cables and protective case Test Head Cable Length: 3 ft (90 cm) |
| Power: Uses four readily available, CR123A 3V long life batteries | *To test concrete and acquire data, the CTG-2 system must be used with a Windows 7+ computer or tablet running Olson Instrument's WinCTG2 software. The required computer or tablet must be provided by the user. |
