Ultrasonic Thickness Gauge

Ultrasonic Thickness Gauge — Non-Destructive Wall Thickness Measurement

The Ultrasonic Thickness Gauge is a handheld non-destructive testing instrument used to measure the wall thickness of pipes, tanks, pressure vessels, structural steel, cast iron components, and coated surfaces from one side only — without needing access to the back face. A single-element or dual-element transducer emits an ultrasonic pulse that travels through the material and reflects from the back wall; the instrument measures time-of-flight and converts it to thickness using the material sound velocity.

JS Civil Lab Solutions supplies ultrasonic thickness gauges for corrosion inspection, pressure vessel integrity assessment, and structural steel evaluation in civil, oil & gas, and power sector projects.
