  • Echo 8 ZH’s enhanced acoustic impedance reduces surface roughness acoustic noise.​
  • Echo 8 ZH covers a broad range of ultrasonic applications.
  • Echo 8 ZH applications include flow metering and long term monitoring at elevated  temperatures.
  • Echo 8 ZH resists drying, allowing long term coupling without reapplication and is the best choice for long-term monitoring, such as flow metering.
