Overview
Echo Ultrasonics is the world leader in developing and manufacturing ultrasonic couplants, including specialty application and high-temperature couplants. Couplants developed for shear and guided wave transmission, for extremely rough surfaces, for pencil probe inspections, for spot welds, for extremely cold and extremely hot applications. Echo has a couplant for all your UT needs. Echo has developed a line of UT cables like you've never seen before. Echo has addressed frequent causes of UT cable failures with this new line of single and dual element UT cables. No more stiff, cracking, and coiling PVC cables with Echo's silicone cables that remain flexible down to -40° F/C. Eliminate the burn risk of armor with Echo's fiberglass sheathed, more flexible, and lighter weight high-temperature cables.
