45MG Ultrasonic Thickness Gage: |  |
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.
Corrosion Measurements with Dual Element Transducers
Precision Measurements with Single Element Transducers
Standard FeaturesIn 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.
| Optional FeaturesFrom a simple corrosion gage to a multi-purpose precision thickness gage with only a few key strokes. The 45MG offers five code-activated software options that makes it one of the most versatile thickness gages in the industry.

Software Options
The 45MG offers five code-activated software options that makes it one of the most versatile thickness gages in the industry.
Echo-to-Echo / THRU-COAT® Option
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
|
 Auto Echo-to-Echo mode with A-scan |  THRU-COAT mode showing thickness of coating and steel (waveform not activated) |
 Manual Echo-to-Echo adjusting the First Echo blank |  THRU-COAT mode with optional waveform |
Single Element Software Option
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.
- Most materials, from thin to thick
- Plastic bottles, tubes, pipes, sheets as thin as 0.08 mm (0.003 in.)
- Metal containers, steel coils, machined parts as thin as 0.10 mm (0.004 in.)
- Cylinder bores, turbine blades
- Glass bulbs, bottles
- Thin fiberglass, rubber, ceramics, and composite materials
- Curved areas or containers with small radii
Single Element High Penetration Software Option
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.
- Most thick or sound-attenuating materials
- Thick cast metal parts
- Thick rubber tires, belts
