Dakota MX-2 UT Thickness Gauge

The Dakota Ultrasonics MX-2 is a fixed velocity thickness gauge. This affordable precision tool requires no special training to operate and is able to measure the thicknesses of common materials from 0.025 to 19.999 inches (0.63 to 500 millimeters) with the appropriate transducer. The standard 5MHz transducer has a range of 0.04 to 6.0″ on steel.

The Dakota MX-2 ultrasonic thickness gauge is ideal for the person that tests a few different materials regularly. Featuring 8 common preset material types and 2 user programmable types, the Dakota MX-2 ultrasonic thickness gauge is a little more flexible for those users that have a need to measure more than one material type. A simple PC program allows the user to program the Dakota MX-2 ultrasonic thickness gauge for two additional set material types.

Dakota MX-2 ultrasonic thickness gauges are packaged in an all metal case, sealed with gaskets to protect them from harsh working environments. This gauge can go anywhere you go while making fast accurate measurements which saves you time and money. Dakota Ultrasonics offers quality gauges that are reliable, innovative and competitively priced with the longest warranty in the business – 5 full years.

The Dakota MX-2 ultrasonic thickness gauge ships complete with a standard transducer (this transducer can be substituted for another model, please contact us for details), couplant, manual, plastic carrying case, certificate of calibration and AA Batteries.

UT Thickness Gauge - MX-3

Measuring Range in Steel
0.040 – 6.00 inches
1.00 – 150.0 mm

The new Dakota Ultrasonics MX-3 Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals, ceramics, glass and most rigid plastics – from only one side!

The Dakota Ultrasonics MX-3 can be used in a Single Thickness Reading mode or in a Scan mode , where the probe is dragged over a large measuring area. The minimum thickness reading recorded during the “scan” will be displayed.

The Dakota Ultrasonics MX-3 probe is waterproof and can be submerged in water. The gauge is impact-resistant and environmentally sealed to provide trouble-free operation under the toughest field conditions.
