Echo 8 ZH is intended for ultrasonic coupling where elevated temperature, surface roughness or long coupling time-frames present coupling difficulties. Will maintain its paste like viscosity throughout its effective operating range for extended time periods.
Applications include flow metering and long term monitoring at elevated temperatures. Resists drying, allowing long term coupling without reapplication and is the best choice for long-term monitoring, such as flow metering.
