Dual and Single Element Underwater Measuring

The UX2 is an underwater material and coating thickness gauge, designed for offshore inspections and rated to a depth of 1000 feet (300 meters). The UX2 is very versatile, offering both Dual & Single element transducers. Equipped with multiple measurement mode options, the UX2 will meet all your application requirements. Onboard 5,000 point data logger, all UX2 settings stored for each measurement, along with an actual A-Scan waveform. The DakView PC or MAC OSX software makes this a very functional kit.

Pulse-Echo Mode (P-E)

Pulse-Echo (P-E) Mode measures from the surface to the back-wall echo. It is used on bare material to determine wall loss on corroded, eroded and pitted materials. When measuring through a coating the measurement will include an error due to the coating thickness x 2-3 because of the difference in sound velocity between the coating and test material.

Echo-Echo (E-E) Mode

Echo-Echo (E-E) Mode measures from the back-wall echo to its multiple-echo and eliminates the error due to the coating. Measurements can only be made on materials that have parallel surfaces as the multiple-echo will disappear if the back-wall is corroded or pitted.

Pulse-Echo-Coating (PECT) Mode - Coating On

Measures Thru-Coating, detects pitting and measures when Echo-Echo (E-E) mode fails. PECT is a unique method that provides the benefits of Pulse-Echo (P-E) and Echo-Echo (E-). Measure coated material without errors caused by the coating while being able to measure on materials with corroded and pitted back-walls.
