Dakota Ultrasonics MX-2

Discontinued replaced with ZX-1

The Dakota Ultrasonics MX-2 ultrasonic thickness gauge is a fixed velocity gauge making it an affordable precision tool that requires no special training to operate.  The Dakota Ultrasonics MX-2 ultrasonic thickness gauge has two user-programmable velocities and 8 pre-programmed velocities to measure the thickness of aluminum, steel, stainless steel, cast iron, plexiglass, PVC, polystyrene, and polyurethane-making the Dakota Ultrasonics MX-2 and ideal model for the person who tests a few different materials regularly.This small, lightweight, water-resistant unit is easy to use and designed for the harshest environment.
