Product Details

UT568B visualizes sound sources in real-time on the screen by overlaying acoustic data onto video images. Simply adjust the frequency and dynamic range to meet most testing needs. Supports photo/video recording and expandable high-capacity data storage for quick analysis.

Features:

  • 138 high-sensitivity digital MEMS microphones in a spiral array.

  • Multiple working modes: Partial Discharge (PD) detection, gas leak detection, and abnormal noise detection.

  • Maximum sound sampling rate: 200kHz.

  • Imaging frequency range: 2kHz – 100kHz.

  • Minimum leak detection limits:

    • At 0.5m distance (0.5MPa): Detects leaks as small as 0.15ml/s.

    • At 1m distance (0.5MPa): Detects leaks as small as 0.2ml/s.

  • Localization distance: 0.3m to 150m.

  • 4.3-inch color capacitive touchscreen for taking photos, recording videos, and viewing files.

  • Text and voice annotations for easy data recording.

  • Expandable storage: Supports TF cards up to 128GB.

  • Wireless connectivity: Wi-Fi and Bluetooth supported.

  • PC Software: Automatically import/export data to view time-domain waveforms, spectrograms, and PRPD (Phase Resolved Partial Discharge) patterns.

  • Super-hearing function: Heterodynes/down-converts ultrasonic sounds for listening via headphones.

  • Built-in focusing function: Concentrates the acoustic cloud image into a small area, reducing interference from other background noise.

  • Adjustable dynamic range for the acoustic cloud size, making it easier to spot smaller leaks.

  • File management: Create, delete, and switch between testing target folders.
