    Product Description
    Dakota Ultrasonics CMXDL Data-Logging Ultrasonic Coating and Wall Thickness Gauge Z-171-0003

    Range: 0.025 - 9.999 inches - 0.63 - 254.0 mm

    Resolution: .001" (0.01 mm)

    Datalogging: YES

    The Dakota Ultrasonics CMXDL Data-Logging Ultrasonic Coating and Wall Thickness Gauge Z-171-0003 measures both coating and wall thickness quickly and accurately—from only one side. In addition, when switched to Pulse-Echo mode, the CMXDL automatically measures and eliminates the coating from the wall thickness measurement, enabling the user to locate the finest corrosion and pitting—without removing the coating

    Oversized graphic LCD is backlit and features easy to read fonts, graphics and display codes showing all critical settings including Velocity, Operating Mode, Alarms, Scan Mode and more. The backlight can be set to ON (always-on), OFF (always-off) or AUTO (automatically-on when measuring).

    Five user-selected operating modes are included:

    • Coating On: Measures wall thickness using Pulse-Echo. It separately displays wall & coating thickness.
    • Coating Off: Measures wall thickness using Pulse-Echo. It displays wall thickness only.
    • Temperature Compensated: Measures wall thickness using Pulse-Echo and automatically adjusts calibration to compensate for changes in material temperature.
    • Thru-Coat: Measures wall thickness only using Echo-Echo. (coating is NOT included)
    • Coating Only Mode (CT): (Coating Thickness) Measures from 0.0005 to 0.100 inches (0.013 to 2.540 mm). Range will vary slightly depending on the coating
