Introduction
The MMX-7 v2.0 has all the features of a ZX pressure gauge plus some other features and benefits. Selectable large digital and B-scan display options, internal 4Gb SD memory, alphanumeric data storage format, 64 user-defined settings, transducer list for improved linearity, echo echo via paint at the touch of a button, multiple calibrations and optional material type options, and more. It's all nicely packed in a very small portable aluminum profile for durability and portability! Our Java-based DakView PC or MAC OSX software and USB-C connectivity make this a complete toolkit!
Product Applications
Corrosion & Pitting, Boilers, Tubes, Glass, Chariots and many other applications.
Instrument display structure diagram

A. Repeatability/Stability Indicator – This indicator should generally be used in conjunction with the numeric thickness values displayed. When all vertical bars are fully lit and the last digit of the digital thickness value is stable, the MMX-7 reliably measures the same value 250 times per second (250 Hz).
B. Battery icon – indicates the remaining battery life of the MMX-7.
C. Speed – The velocity value of the material currently used or calibrated by the MMX-7. Displays in imperial or metric units, depending on the unit in which the gage is set.
D. Feature Status Bar – Indicates the features that are currently enabled and in use in the following order:Measurement Mode,Difference mode,High-speed scanning mode,Alarm mode,Gain setting.
E. Numeric Material Thickness Values – Extra-large font size for easy viewing.
F. Scan Bar – Another view of the material thickness in the horizontal bar of the deflection style. This is a vision tool that enables users to see thickness changes from defects and pits during high-speed scanning.
G. Units – The units of measurement (imperial, metric) currently in use.
H. Numeric Material Thickness Values – Smaller font size when B-scan display view is enabled.
I. Minimum material thickness – part of the scanning function. Displays the minimum thickness value found during the scan.
J. Maximum material thickness – part of the scanning function. Displays the maximum thickness value found during the scan.
K. B-scan display – cross-sectional view of the material. Provide the user with a graphical view of the relative/blind surface (i.e., the inner surface of the pipe wall) to give the user an idea of the condition or integrity of the material being measured.
