Concrete Thickness Gauge

OLSON INSTRUMENTS (Made in USA) Portable Concrete Thickness Gauge for verifying Concrete slab thickness and integrity (No Coring, No Drilling, No Excavating)

Meets ASTM Standard C1383

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.

Application
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)
