The Olson Instruments CTG-2 Concrete Thickness Gauge 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. This thickness gauge requires no special training: simply connect the CTG-2 to a compatible laptop or tablet and start testing with Olson's WinCTG2 software. For greater accuracy, calibrate the CTG by testing a point of known concrete thickness to obtain the concrete velocity for that job.

The Olson Instruments CTG-2 features a ruggedized, hand-held test head with an integrated displacement transducer and solenoid impactor. No coupling agents are required for use of test head on concrete, and it works well on elevated decks or graded platforms. This gauge works on ceramic tiles, paint, and epoxy and is equipped with easy velocity calibration at the known thickness location. If no such location is available, Olson provides useful default parameters set to meet the latest industry standards.
