Echo Z+ is a high acoustic-impedance ultrasonic couplant. It increases acoustic impedance and decreases surface noise, making it ideal for very rough, pitted, corroded surfaces or tight-curved test objects, and concrete.
Echo Z+ contains no VOCs, naptha, oil, hydrocarbons, silicones, petroleum distillates, dyes or fragrance.
Contains a short term ferrous corrosion inhibitor. Echo Z+ contains glycerin and is intended to be removed from non-ferrous metal parts after inspection.
