Ultrasonic Thickness Gauges


Ultrasonic thickness measurements are accurate, reliable and repeatable. Instant digital readings can be achieved by transmitting sound into a material from one side only, making it unnecessary to destroy parts. Corrosion thickness gages measure the remaining wall thickness of parts that are subject to corrosion or erosion. They generally employ dual element transducers that have separate pulser and receiver transducer elements to provide better sensitivity on rough or corroded parts such as pipelines, storage tanks, pressure vessels, hulls and steam lines. In general, ultrasonic thickness gages can be used to measure metals, plastics, glass, rubber, composites and most other engineering materials.





The 27MG is a basic ultrasonic thickness gage designed to make accurate measurements from one side on internally corroded or eroded metal pipes and parts. It is lightweight, durable, and ergonomically designed for easy, one-hand operation.


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.


The versatile 38DL PLUS can be used with dual element transducers for the measurement of corroded pipes to the very precise thickness measurements of thin or multilayer materials with a single element transducer.

Magna-Mike 8600

The Magna-Mike is a Hall Effect thickness gage that uses a magnetic probe to perform accurate measurements on nonferrous and thin materials such as plastic bottles.

35 RDC

The 35RDC is a simple Go/No-Go ultrasonic gage designed to detect subsurface defects caused by impact damage on aircraft composite structures.

Transducers and Accessories

Olympus offers a variety of single and dual element transducers and accessories for precision and corrosion thickness gaging.
