Twin Crystal Ultrasonic Probes

Particularly suited to measuring heavily corroded metals in either Echo-Echo or Single-Echo mode.

Twin crystal probes are particularly suited to measuring heavily corroded metals. They are used with our gauges in two measuring modes. In Echo-Echo mode, up to 1 mm (0.040 inch) of surface coating can be read through and ignored. Single-Echo mode should only be used when there are no surface coatings.
