The 45MG is an advanced ultrasonic thickness gage packed with standard measurement features and software options. This unique instrument is compatible with the complete range of Olympus dual element and single element thickness gage transducers, making this innovative instrument an all-in-one solution for virtually every thickness gage application.
In its basic configuration the 45MG is a simple and straightforward gage that requires minimal operator training to tackle most common thickness gaging applications. With additional optional software options and transducers however, the 45MG can become significantly more advanced and take on applications well beyond that of a typical entry-level gage. Furthermore, most options are available individually at the time of purchase or can be added in the future as your needs change.

The 45MG offers five code-activated software options that makes it one of the most versatile thickness gages in the industry.
Echo-to-Echo
The gage displays the true metal thickness and ignores the thickness of the coating layer, using multiple back-wall echoes:
THRU-COAT Technology
| Uses a single back-wall echo to measure true metal thickness. You can display the metal and coating thicknesses, each adjusted for their correct material sound velocities. There is no need to remove paint and coatings from surfaces. THRU‑COAT measurements use the D7906-SM, D7906‑RM, and D7908 dual element transducers. |  |
The Single Element software option enables you to make very precise thickness measurements at a resolution of up to 0.0001 in. or 0.001 mm. Compatible with single element Microscan transducers ranging from 2.25 MHz to 30 MHz.
This option allows you to use low frequency single element transducers (as low as 0.5 MHz) to measure thick or highly attenuating materials such as rubber, fiberglass, castings, and composites. Included is the Single Element option.
The 45MG has a full-featured internal bidirectional alphanumeric data logger that is designed to easily store and transfer thickness readings and waveform data. The data logger option includes the GageView™ Interface program.
Data Logger Option
When viewed on your PC a color coded grid easily flags out-of-tolerance thickness conditions.
Measurement reports can easily be generated and printed containing measurements, ID, and other parameters.
Onboard DB Grid View with three programmable colors
GageViewInterface Program
When viewed on your PC a color coded grid easily flags out-of-tolerance thickness conditions.
This optional Live A-scan mode allows users to view the ultrasound waveform (or A-scan) directly on the gage's display, verify the thickness measurement, and make manual adjustments to gain and blanking settings to maximize measurement performance in challenging applications. This helpful option features Manual Gain Adjust, Extended Blanking, First Echo Blank, Range, and Delay.
Olympus NDT offers a complete selection of transducers, cables, couplants, calibration test blocks, and accessories to meet a wide variety of ultrasonic precision thickness gaging applications.
