Ultrasonic Thickness Gauge MMX-6/MMX-6DL

MMX-6 Multi-Mode Ultrasonic Thickness Gauge

The MMX-6 is a Multi-Mode thickness gauge that has the ability to measure through painted or coated surfaces and eliminate the thickness of the paint using a dual element style transducer in echo-echo mode. The MMX-6 can also effectively find pits and flaws with the press of a single button. The MMX-6 has all the features of the MX-3 plus: An audible and visual alarm mode. In alarm mode, the user can set a nominal thickness value. When measurements fall above or below the set nominal value, a red light and audible beeper is displayed and sounded. The MMX-6 is also equiped with an RS232 port out. This enables the user the ability to send measurements to an external data collection device or directly to a PC.

MMX-6DL Data Logger Ultrasonic Thickness Gauge

The MMX-6DL has all the features of the MMX-6 plus: An Internal data logger that stores a total of 1000 readings in 10 files of 100 readings each file. This gives the user the ability to store, and download the stored measurements directly to a PC using our DakView software program. The software and transfer cable are included in the MMX-6DL kit.


The MMX-6 series thickness gauge is a simple to use hand-held Ultrasonic Thickness Gauge with the ability to measure through paint and coatings and eliminate the thickness of the paint or coating. The MMX-6 uses a dual element style transducer. With the single press of a button, the MMX-6 can be switched between pit or flaw mode ( pulse-echo), and through paint/coatings mode (echo-echo) for maximum inspection efficiency. The MMX-6 is equipped with a bundle of features to make your job eaiser: Alarm mode, high speed scanning, and data send are the main features of the MMX-6.

The MMX-6 series come as a complete kit, ready to use, and is backed by 5 year limited warranty.
