Echo 8 ZH™

Echo 8 ZH™ is a specialty ultrasonic couplant designed for applications where elevated temperatures, rough surfaces, or extended coupling durations make reliable sound transmission challenging. Its paste-like viscosity remains stable throughout the operating range, allowing consistent coupling over long time frames without drying or reapplication.

Formulated with enhanced acoustic impedance, Echo 8 ZH™ reduces surface roughness–related acoustic noise and improves signal quality across a wide range of ultrasonic inspections. It is particularly well suited for long-term monitoring applications, including flow metering and other inspections requiring sustained coupling at elevated temperatures.

Echo 8 ZH™ delivers dependable performance in demanding environments where standard couplants may fail, making it an ideal choice for both short-term inspections and continuous monitoring programs.
