MMX-6 Ultrasonic Thickness Gauge
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.

Features
Multi-Mode: Toggle between Pit/Flaw detection (Pulse Echo Mode), and through Paint/Coatings (Echo-Echo Mode) with the single press of a button.
Alarm Mode: Enter a minimum acceptable thickness value. If measurement falls below minimum, red led will illuminate and sound beeper. If measurement is above minimum value, green led will illuminate.
Data Ouput: RS232 output sends thickness readings to a computer or other external storage device.
