Doppler provides existing solutions for most corrosion applications, offering a complete set of dual-crystal and single-crystal thickness gauge probes for workpiece thickness measurement. Combined with Accur 1/3/5 thickness gauges, they maximize the accuracy of thickness measurements. Besides measuring corrosion wall thickness, they can also be used for measuring and applying thicknesses to small-diameter pipes, oil pipes, boiler tube walls, penetrating coatings, and spot weld integrity. Probes are available with different frequencies, contact sizes, and for special high-temperature applications.
