Dakota NDT MMX-7 Multi-Mode Ultrasonic Thickness Gauge
SKU: Z-160-0003
A multi-mode ultrasonic thickness gauge with thru-paint measurement, time-based B-scan and a 12,000-reading data logger, made for corrosion monitoring and wall thickness inspection.
| 2Measurement modes | 12,000Readings and waveforms | 0.001"Resolution | 5 MHzHD probe included |
The Dakota NDT MMX-7 is a multi-mode ultrasonic thickness gauge for corrosion monitoring, wall loss evaluation and field calibration on a wide range of materials. Inspectors can switch between pulse-echo mode for pits and flaws and echo-echo mode for measuring through paint and coatings, using one highly damped dual-element probe for both.
A time-based B-scan shows a cross-section of the test material, and the internal data logger stores 12,000 readings with their waveforms. The kit includes a 5 MHz HD probe, PC software and transfer cables, all packed into a rugged, sealed aluminum gauge.
Key Features
 | Dual-element accuracyThe included 5 MHz HD dual-element probe has one crystal to transmit and one to receive, separated by an acoustic barrier. This creates a V-shaped sound path, which the gauge corrects for to give an accurate thickness reading, with a built-in transducer table for improved linearity. |
Two measurement modes in one gauge
Pulse-echo mode detects pits and flaws. Echo-echo thru-paint mode ignores the coating and measures only the base material, from 0.100" to 1.0" with coatings up to 0.040", so less surface preparation is needed.
Time-based B-scan
The B-scan view displays a cross-section of the test material, giving a graphical profile of the bottom surface for corrosion mapping and wall loss evaluation.
12,000-reading data logger
Store readings together with their waveforms, then transfer them through the data output port using the included PC software and cables.
High-speed scan and alarm mode
Scan mode captures readings quickly as you move across the surface. Alarm mode lets you set high and low limits, with a visual and audible warning when a reading falls outside them.
Custom setups and calibration
Store up to 64 custom setups alongside factory setups for common applications. Calibrate with single or two-point calibration, or pick a basic material type, and choose low, medium or high gain for different materials.
Rugged sealed case
An extruded aluminum body with gasket-sealed, nickel-plated end caps protects the gauge in demanding field conditions, and the backlit display stays readable in low light.
