UT-110 Ultrasonic Thickness Gauge


The UT-110 ultrasonic thickness gauge is our basic readout unit which includes automatic probe recognition, automatic zeroing and a large, easily-read LCD.

The PTc UT-110 ultrasonic thickness gauge can measure with very high resolution (0.01 mm or 0.001 inches) the thickness of metallic and non-metallic materials such as steel, aluminum, titanium, plastics, ceramics, glass and any other good ultrasonic wave conductor. The UT-110 ultrasonic thickness gauge accurately displays readings in either inches or millimeters.

The standard probe, D5008 is 5 MHz and has an 8-mm -diameter crystal, 11-mm-diameter contact and a maximum operating temperature of 60°C.  Minimum measurement dimensions are (1) 20 mm diameter and (2) 1.2 mm thickness.


  • Accurately displays readings in either inches or millimeters
