Our History

Our industrial ultrasonic couplant history began in Pennsylvania in the early 1960s. With each company, founder Gene Larson has focused on optimizing couplant performance, improving the chemical safety profile and increasing the operating limits. We have been manufacturing couplants in Bellingham Washington since 1992.
