Measuring Modes – Multiple-Echo using 3 sound pulses to ignore coatings up to 20mm thick, Echo-Echo using 2 sound pulses to ignore coatings up 1mm thick, Single-Echo using 1 sound pulse.

Materials – Sound velocities between 1000 – 9000 m/s – covers virtually all common engineering materials.

Accuracy – ±0.1 mm or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure.

Resolution – Multiple-Echo mode – 0.1 mm or 0.05 mm, Single-Echo and Echo-Echo modes – 0.01 mm.
