Single crystal probes work with Cygnus gauges in Multiple-Echo mode, letting you take measurements through coatings without stripping them first. Which frequency you want depends on how thin the material is - lower frequencies punch through thicker coatings and corrosion, while higher frequencies suit thinner walls. The 2.25MHz 13mm probe is the standard choice for most jobs, but the range runs from a 5.0MHz 6mm probe for small diameter pipes and tubes up to a 2.25MHz 19mm probe for large, heavily corroded flat plate.

Where the surface is pitted or heavily corroded, twin crystal probes maintain signal better. Browse all ultrasonic thickness gauges
