Dakota Ultrasonics CMX DL+ Thickness Gauge

The CMX DL+ gauges have all the features of the basic CMX models, plus a full-featured A-Scan presentation with RF and Rectified viewing options. The CMX DL+ is equipped with 3 fully independent gates (start, stop, width, & Threshold). Equipped with a 110dB gain range for added flexibility with a variety of transducer types and applications. Selectable 50-volt pulser boost or cut (100 – 200 volts). The color version offers a rotating portrait or landscape option to increase the A-Scan viewing area. Our DakView java-based PC or MAC OSX software makes this kit truly the Cadillac of the CMX series.
