Ultrasonic thickness gauges provide NON-DESTRUCTIVE and NO-DAMAGE measurement solutions to the part being inspected.
Olympus NDT is a leading unit in thickness measuring equipment for high accuracy and meets the testing requirements of almost all types of materials.
They include a wide range of features from basic to advanced, with different activation codes it will become the most amazing and professional tool today.
Olympus NDT Thickness Gauge Nowadays, it can measure almost all types of materials such as metals, plastics, glass, synthetic materials, composites, rubber, castings, objects with high sound attenuation...
Ultrasonic thickness gauges and flaw detectors use the same basic principle. Both use a transducer that generates ultrasonic waves, and both measure the time it takes for the ultrasonic signal to leave the transducer, travel through the material, strike a reflecting surface, and return to the transducer.
All devices use the basic equation:
Distance = (Speed * Time)/2
The reflection and transmission of high-frequency sound waves – known as ultrasound – has long been an important tool for assessing weld integrity, as well as inspecting structural metals, pipes and tanks, boiler tubes, railroad tracks and axles, aerospace composites, and many other industrial applications.
Industrial ultrasonic testing equipment is popular because:
The device uses ultrasonic method to determine the actual thickness of the test part with very high accuracy. They can meet many demanding applications in work, such as: Testing thickness from very thin to very thick, testing surfaces with extremely low to extremely high temperatures, measuring through the coating without removing them (can display both the thickness of the base metal and the coating), measuring through the outer Oxide/rust layer without removing them and using a couplant, measuring the Oxide/rust layer on the inner pipe wall without direct contact (can display both the thickness of the base metal and the Oxide/rust layer), measuring through multiple layers (displaying the thickness of each layer and the total of the layers), measuring materials with high sound attenuation such as castings, rubber, composites, synthetic fiberglass..., or plastic and glass materials.

The device uses a magnetic method with the Hall effect mounted in the measuring head, measurements are made at the distance between the tip and the ball placed on the other side of the part to be tested.
The device has high precision with tolerance ± [(accuracy x thickness) + 0.003 mm], and it can test materials such as Bottles, jars, trays or plastic or glass items, non-magnetic alloys, aluminum materials, medical packaging, heterogeneous materials, paper or foam containing products, food in industry or medicine, plywood, particle board, wooden floors, engineered wood, plastic ceiling panels, etc.
The Magna-Mike 8600 is a simple magnetic method for reliable measurements on non-magnetic materials, and is very simple to operate. Measurements are made when the magnetic probe moves over the surface of the test piece and the ferromagnetic ball (or disc or wire) is placed on the opposite side of the test piece. With the Hall effect technique at the tip of the probe and the ferromagnetic ball (or disc or wire), the measurement results are displayed instantly on the Magna-Mike 8600's color LCD screen.
Magna-Mike 8600 This is a handheld device so it can be used in one place or moved to where needed. With a remote foot switch, the device can give us fast testing time and large volume.
The Magna Mike measuring range is from 0.001 mm (0.0001 in.) to 25.4mm (1 in.). Multiple target options extend measurement capabilities and accuracy.
