Standard Features
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.
• Compatible with full line of Olympus dual element
transducers for thickness measurements on internally
corroded metals
• Min./Max. mode
• Two Alarm modes
• Dierential mode
• Time-based B-scan
• Reduction Rate
• Gain Adjust (standard, high, and low)
• Password instrument lock

Optional Features
From a simple corrosion gage to a multi-purpose precision thickness gage
with only a few key strokes
The 45MG oers five code-activated software options that
makes it one of the most versatile thickness gages in the
industry.
Echo-to-Echo / THRU- COAT
Using Echo-to-Echo, the true metal thickness is displayed
and the thickness of the coating layer will be ignored.
THRU-COAT measures metal and nonmetallic coating thicknesses, each adjusted for their correct sound velocities.
There is no need to remove paint or coatings from surfaces.
Single Element
For very precise thickness measurements on many materials, including metals, plastics, composites, glass, and ceramics. Compatible with single element Microscan transducers ranging from 2.25 MHz to 30 MHz.
Single Element High Penetration
For thickness measurement on thick or highly attenuating
materials such as fiberglass or cast metals. Compatible with
single element Microscan transducers ranging from 0.5 MHz
to 30 MHz. Included is the Single Element option.

Data Logger
The 45MG has a full-featured internal bidirectional alphanumeric data logger that is designed to easily store and transfer
thickness readings and waveform data. Includes GageView™
interface program, a Windows-based application.
Live A-scan with Waveform Adjust
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.

Thickness Measurements on
Internally Corroded Metals
Using Dual Element Transducers
One of the major applications of the 45MG is measuring
the remaining thickness of pipes, tubes, tanks, pressure
vessels, ship hulls, and other structures aected by corrosion or erosion. Dual element transducers are most commonly used for these applications.
• Automatic Probe Recognition for standard D79X series
dual element transducers
• Calibration Doubling warning when echo doubling may
occur during calibration
• The Echo-to-Echo / THRU-COAT® option allows for
measurements on painted and coated surfaces
• High temperature measurements; up to 500 °C (932 °F)
B-scan Mapping (Time-based)
The 45MG gage B-scan feature converts live thickness
readings into cross-sectional images drawn on the display.
This standard feature is very helpful in viewing the changes
in thickness measurements over a distance. The B-scan
is activated as soon as the transducer makes contact with
the surface of the material. The Freeze Minimum function
is used to display the minimum thickness of the scanned
area. The optional 45MG datalogger can store up to
10,000 thickness readings in a single B-scan.
High-Temperature Surfaces
The 45MG is ideally suited for making stable thickness
measurements on hot material surfaces (up to 500 ºC or
932 ºF) with the D790 series transducers (D790, D790 -SM,
D790-RL, and D790-SL). The Zero Compensation feature of
the 45MG enhances the accuracy of measurements on hot
surfaces by compensating for temperature changes in the
transducer delay line due to thermal drift.
