Sonagel W - Water based Couplant

Couplant type W,  Water Based, ready to use gel

This couplant is designed for use on all types of metallic surface and is especially suited to solving the problems of rough, pitted, uneven surfaces to allow smooth probe movement during testing.

The thixotropic properties of this couplant give excellent wetting and acoustic transmission and do not allow the product to flow all over the test area; and so is very economical to use as you only cover the working area not the whole piece.
