Economical Ultrasonic Couplant
Echogel® is an economical, basic-use couplant for ultrasonic inspections, like flaw detection/sizing and thickness gauging, where salt cake or metal corrosion salts are present. It provides good corrosion inhibition and resists viscosity breakdown on salt-caked boilers and other corroded materials.
Echogel comes in two different viscosities, Echogel 14 which is a thin, flowable gel and Echogel 20 which is a medium-thick gel.
