Sonagel LTHT High Temperature Ultrasonic Couplant (ZZZ/0015)

Sonatest’s Sonagel LTHT high temperature ultrasonic couplant (up to 300°C / 572°F) is designed for use on all types of metallic surfaces and allows smooth probe movement during testing, at elevated temperatures. This gives good probe contact and acoustic transmission and prevents flow over the test area. It is very economical to use as you only cover the working area and not the whole piece.

Usually supplied in a 1Ltr container but smaller containers are available, please contact us for more information.

Water-based and oil-based couplants are also available.
