Beha-Amprobe ULD-410-EUR Ultrasonic Leak Detector

The ultimate ultrasonic diagnostic tool for HVAC/R, mechanical and electrical inspection and troubleshooting

When equipment begins to fail due to an air or gas leak or vibration, or electrical discharge, the leakage point emits an ultrasonic sound wave that is above the natural range of human hearing. The ULD-400-EUR Series Ultrasonic Leak Detectors convert this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure.

See the strength of the leak clearly on the large LCD display bargraph and identify the source of the leak by listening to the converted audible sound emitted via the headphones. When working in unpressurized systems, or the pressure is not sufficient enough to detect or verify a leak with the Receiver alone, use the Transmitter to generate the ultrasonic signal (included with the ULD-420-EUR kit). In extremely noisy environments where there is strong ultrasonic noise generated by running machinery or equipment, the Receiver’s filter function can filter out up to three main noise frequencies which would otherwise hide the noise of the fail.

The ULD-410-EUR Comes Supplied With:

  • ULD-400-RE Receiver
  • Headphones
  • Earbuds (for use with hard hat)
  • PB-1 Power Parabola
  • TEA-1 Flexible Tubing Adapter
  • TE-1 Tubular Extension
  • CC-ULD-400 Hard Carrying Case
  • AA Batteries (Receiver)
  • User Manual


Ideal for inspecting:
• Compressed air or other gases (Do not use ULD-400-EUR for combustible gas leak detection)
• Plumbing
• Electrical and mechanical systems
• Valves, tanks and pipes
• Heat exchangers, boilers and condensers
• Air conditioning and refrigeration systems
• Motors and machinery

Key Features:

• 6.35 cm LCD display with bargraph
• 20 kHz to 90 kHz frequency range: optimal range for detecting a variety of leakage events
• Quality headphones to help identify the source of the leak
• Parabola accessory directs the ultrasound towards the sensor

Product Information

• Three filters to remove main noise frequencies in noisy environments
• Adjustable Receiver sensitivity and Three Transmitter signal strengths for accurate leak pinpointing
• Detachable Tubular Extension provides additional reach in hard to reach areas
