Price: $ 2,575.00

Dakota Ultrasonics CMX1-DL (CMXDL) Data-Logging Ultrasonic Coating Thickness Z-171-0003 / Z-171-0005
Range: 0.025 - 9.999 inches - 0.63 - 254.0 mm
Resolution: .001" (0.01 mm)

The Dakota Ultrasonics CMX1-DL (CMXDL) Data-Logging Ultrasonic Coating Thickness Z-171-0003 / Z-171-0005 measures both coating and wall thickness quickly and accuratelyfrom 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 pittingwithout 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
