  • Smart Operation
    Multifunction joystick, shortcut keys and automatic calibration (velocity, delay, angle) reduce setup time and streamline inspections.
  • Dual-Gate Detection
    Gate A auto-tracks echoes while Gate B enables full-screen zoom for precise sizing and analysis.
  • Automated Efficiency
    Preset parameters, DAC curve presets with auto-adjusted evaluation lines and 50-channel memory accelerate repeat inspections.
  • High-Resolution Imaging
    400 MHz real-time sampling paired with a 20 MHz low-noise amplifier delivers clear, stable defect visualization.
  • Rugged and Portable
    IP-rated protection with shock resistance for reliable overhead and field inspections.
