Ultrasonic Thickness Gauge- MMX-6 DL

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

The MMX-6 and MMX-6DL have not only been combined with all the durability and features of the MX series gauges, but have also been equipped with the ability to measure through painted or coated materials and eliminate the thickness of the paint or coating. Our 5 year limited warranty indicates how we feel about the reliability and durability of the new MMX Series.
