Thickness Gauge Rentals

These instruments are used whenever the corrosion of steel and its thickness is a concern or to inspect coatings. Our ultrasonic thickness gauge rentals are commonly used for measuring the material thickness of pipes, tanks, ship hulls, and various containers or pressure vessels. While our holiday detector rentals are used to inspect the coating. Ultrasonic thickness gauges can take highly accurate thickness measurements from one side of the material and have a wide range from as thin as 0.04 inches up to 20 inches thick at a resolution of 1/1000th of an inch. Our holiday detectors are easy to use and allow you to quickly find abnormalities in coatings before material deterioration.

Extech TKG250

Ultrasonic Thickness Gauge - Material Thickness

Extech TKG250

The TKG250 is an advanced ultrasonic thickness gauge that remains easy to use for simple tasks while still providing advanced features. With many modes including echo to echo for ignoring coatings, B-scan, A-scan, adjustable alarms, differential readings, and real time historical comparisons for corrosion monitoring, the TKG250 is capable of accurately measuring the thickness of steel for the simplest to the most complex jobs. The large color LCD display provides easy to read results quickly and can even display live waveforms. All of our ultrasonic thickness gauge rentals include datalogging and advice from our experienced engineers.
