Ultrasonic Thickness Gauges

Public Works Other Markets

Ultrasonic thickness gauges measure a material's remaining wall thickness non-destructively from a single accessible side, used across infrastructure and asset inspection to check for corrosion, erosion, and wear. Options range from simple, low-cost gauges with basic numeric displays, suited to straightforward spot checks, up to premium instruments with color waveform displays, advanced measurement modes, and datalogging sold by quote at several thousand dollars. Two features drive most of the difference: single- versus dual-element probes (dual-element reads far better on corroded metal and is the standard for infrastructure work), and through-coat capability (measuring base metal beneath paint or coating without removing it). Many manufacturers offer multiple models or generations in this space, each entry represents a typical model rather than the vendor's full catalog.
