Fuji Tecom Digital Sound Detector FSB-8D

Water Leak Detector

Fuji FSB-8D Digital Sound Detector
The Fuji FSB-8D is a high-performance digital sound detector designed specifically for detecting leak sounds in plastic pipes such as PVC and PE. Equipped with an LCD display, advanced notch filters, and high sensitivity, the FSB-8D enables more precise leak detection in noisy environments. With its anti-slip short contact design and low power consumption, this device is an ideal solution for reliable and comfortable field inspections.

Key Features:

  • Advanced Notch Filter
    Effectively reduces interference from vending machines, electrical transformers, and AC power flow noise by eliminating specific frequencies.
  • Anti-Slip Short Contact Design
    Ensures stable sound detection directly from the surface, enhancing accuracy and ease of use.
  • Improved Sensitivity
    Delivers double the intensity and three times higher sensitivity than the previous model (FSB-7D), making it ideal for plastic pipes.
  • Reverse Polarity Protection
    The battery terminal is designed to deactivate the unit if batteries are installed incorrectly and includes a built-in automatic fuse.
