DAKOTA MMX-6 & MMX-6DL Thru-Coating Thickness Gauges
This item has been discontinued, click on the link for the alternative - ZX-6 & ZX-6DL
The MMX-6 has all the features of the MX-5 plus:
- Multi-Mode thickness gauge
- Echo-Echo mode measures through painted or coated surfaces and measures only the base material thickness.
- Zero-First Echo mode effectively finds pitting and measures on severely corroded material
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-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.
- DakView software program and transfer cable are included in the MMX-6DL kit.
- MMX-6 comes complete with probe, carrying case, couplant and operation manual. The MMX-6DL also includes software and transfer cable.
