Dakota Ultrasonics CMX Ultrasonic Thickness Gauge

DAKOTA Ultrasonics CMX Ultrasonic Material & Coating Thickness Gauge adds to the measurement of corrosion defects and wall thickness of painted or unpainted structures, the ability to measure the coating thickness as well. Optional B scan is another feature of this versatile UTG. Dakota CMX thickness gauge is available in standard or data-logging models.


CMX Ultrasonic Material & Coating Thickness Gauge by Dakota Ultrasonics offers the versatility of non-destructive wall thickness measurement of coated or uncoated materials, as well as the ability to measure the thickness of the coatings. The CMX UT gauge offers pulse-echo to a maximum thickness of 19.999 inches, pulse-echo with coating or with temperature compensation, echo-echo mode for measuring up to 4 inch thicknesses through paint and coatings, echo-echo verify, and coating-only measurement modes. CMX-DL Ultrasonic Thickness Gauge with Data-Logging has 32 megabits of memory capacity capable of storing up to 16,000 readings, B-scan image, and gauge settings for every reading with the graphics feature on; with graphics off, store up to 210,000 readings, downloadable to computer using the included RS232 serial cable and Windows-based software.
