Brief
The MMX-6 is a versatile ultrasonic thickness tester that combines features like fast scan and alarm together with multi-mode operation. No need to remove or allow for errors due to paint and coatings. Conveniently toggle between pulse-echo mode (detect flaws & pits) and echo-echo mode (eliminate paint & coating thickness). The MMX-6 uses a highly-damped dual-element transducer for both modes thereby eliminating the need to switch between transducer types.

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.
