Industry solutions, landing pages and articles on Olympus — ultrasonic couplant
Where it is used
Typical tasks
- Ultrasonic thickness gauging for corrosion
- Ultrasonic weld inspection
- Field and laboratory testing
Overview
Couplant is a gel or liquid applied between an ultrasonic transducer and the part surface. Air hardly transmits ultrasound, so without couplant a thickness gauge or flaw detector receives no signal. The couplant type is chosen for roughness, temperature and surface orientation.

How to apply
- Clean loose rust and dirt from the test point.
- Apply a thin layer of couplant.
- Press the transducer and wait for a stable reading.
Applications
- Ultrasonic thickness gauging for corrosion
- Ultrasonic weld inspection
- Field and laboratory testing
Related instruments
Transducers: D790, D791. Gauges: 45MG, 39DL PLUS. Flaw detectors: EPOCH 650.

Olympus (Evident) couplant for ultrasonic thickness gauging and flaw detection: it removes the air gap between transducer and surface, without which ultrasound does not enter the metal. The couplant type is chosen for surface, temperature and orientation.
