The MMX Series has arrived! These gauges are the answer to both versatility and convenience in every way! The MMX series defines versatility by combining features like: Fast Scan, Alarm (audible/visual), and data logging, along with multi-mode for reading through and eliminating the thickness of painted or coated materials. The MMX demonstrates convenience by making all these features available to the user with just the touch of a button. Conveniently toggle between pulse-echo mode (detect flaws & pits), and echo-echo mode (eliminate paint & coating thickness), to cover all your inspection requirements. No need to remove or allow for errors due to paint and coatings. The MMX gauges use a highly damped dual element style transducer for both modes, eliminating the need to switch between transducer types. The MMX gauges are packaged in an all aluminum sealed case, making them rugged and resistant to the working environment— Dakota's trademark. 5 Year Limited Warranty

Built in:

Stainless steel reference disk for probe zeroing.

Four readings per second for single point measurements or 16 per second in Scan Mode – captures the minimum thickness.

Single and Two point calibration option included.

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 printer, computer or other external storage device.
