Echo 8 ZH is a high acoustic impedance elevated temperature long-term monitoring couplant. It is ideal for inspections when there are elevated temperatures and surface roughness or long coupling time frames create coupling challenges. Its paste-like viscosity remains intact across its operating range for long periods.
Echo 8 ZH's improved acoustic impedance lowers surface roughness acoustic noise. Echo 8 ZH can be used for a variety of applications including flow metering and long-term monitoring at elevated temperatures. Echo 8 ZH is designed for long-term coupling (resists drying) without the need to reapply and is the best choice for long-term applications, such as flow metering.
