Dakota MX-3 Ultrasonic Thickness Tester Gauge

Dakota MX-3 Ultrasonic Thickness Tester Gauge is equipped with a two point calibration option, providing the user with extreme accuracy.

Another special feature of the MX-3 is the high speed scan mode. In this mode, the MX-3 takes 16 readings per second rather than 4 readings per second in standard measurement mode.

The readings are viewable while scanning.

Simply remove the transducer from the area being tested and the MX-3 will display the minimum thickness in the area scanned.

SUPPLIED WITH one of the following probes:

  • 1/4 inch 5.00MHz standard probe, and is suitable for most materials, such as the thickness of steel, stainless steel and glass. Also measures aluminium and certain types of thin plastics.
  • Better results can be obtained by using the 1.00MHz probe for the thicker thicknesses of cast iron and extruded plastics such as polypropylene, polystyrene, polyethylene and PVC.
  • Using the 7.50MHz probe, the unit better measures the thicker thicknesses of high tensile steel and aluminium.

Supplied With: 1/4" Probe (transducer) with 1.2m lead Carry case.

Conformance Certificate Comes with one 1/4 inch Probe: 1.00MHz Probe, 5.00MHz Probe, 7.50MHz Probe
