Dakota MMX6 Ultrasonic Thickness Gauge

The MMX-6 Ultrasonic Thickness Gauge is a simple-to-use, hand-held ultrasonic thickness gauge that measures material thickness through paint and coatings, disregarding the coating thickness.

Using a dual-element transducer, the MMX-6 can be switched between pit or flaw mode (pulse-to-echo) and through coatings mode (echo-to-echo) with a button-push. MMX-6 is ideal for corrosion and pitting evaluation of pipelines, tanks, boilers, glass, and other materials.


Features of the MMX-6 Ultrasonic Thickness Gage include:

  • alarm mode
  • high speed scanning
  • data send
  • multi-function LCD display with selectable back-light for easier reading in low-light conditions
  • measurements displayed in inches, inches / microsecond, millimeters, and meters / second
  • bar graph indicates reading stability
  • measuring range:
  • pulse-echo mode (pit and flaw detection) 0.025 to 19.999 inches (0.63 to 500 millimeters)

  • Echo-Echo mode (through paint & coatings)  0.100 to 1.0 inchyes (2.54 to 25.4 millimeters)

  • Velocity range: .0492 to .3937 inches / micro-second (1250 to 10,000 meters/sec)
  • four readings per second for sing-point measurements; 16 readings per secon in scan mode
  • single and two-point calibration option
  • MMX-6 DL Data logging model stores 1000 readings in 10 groups of 100.
  • extruded aluminium body, nickel-plated end-caps
