Description

Description

  • 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.
