Amprobe ULD-420 Kit – The Ultimate Ultrasonic Diagnostic Tool
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 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 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.
Features
• 2.5” LCD display with bargraph
• 20 kHz to 90 kHz frequency range: optimal range for detecting a variety of leakage events
• Three filters to remove main noise frequencies in noisy environments
• Adjustable Receiver sensitivity and Three Transmitter signal strengths for accurate leak pinpointing
• Quality headphones to help identify the source of the leak
• Parabola accessory directs the ultrasound towards the sensor
• Detachable Tubular Extension provides additional reach in hard to reach areas
The ULD-400 is ideal for inspecting:
• Compressed air or other gases*
• Plumbing
• Electrical and mechanical systems
• Valves, tanks and pipes
• Heat exchangers, boilers and condensers
• Air conditioning and refrigeration systems
• Motors and machinery
*Do not use ULD-400 for combustible gas leak detection. The Amprobe GSD600 can be used for propane and methane gas leak detection.
Visual and audible leak pinpointing
While scanning a target area with the Receiver’s microphone sensor, the displayed bargraph will indicate proximity to the source of the leak. Plug the headphones into the Receiver to audibly hear the leak and verify its source. For example, air leaks will produce more of a hissing sound while electric discharge manifests in a ticking sound.
Reduce your utility bill
Air leaks can have a huge impact on the energy efficiency of your whole system. The ULD-405 will help you troubleshoot problem areas where air leaks have gone undetected, reducing your overall financial costs.
Leak not pressurized?
Use the ULD-400-T Transmitter.When a leak is not pressurized sufficiently, or located in an unpressurized system, it is not emitting enough ultrasonic sound for the Receiver to detect it. In these circumstances, use the ULD-400-T Transmitter (available separately or with the ULD-420 kit) to emit the ultrasonic sound readable by the Receiver. The Transmitter is programmed with three signal levels for precise pinpointing of leaks.
The Transmitter can be used to find air and water leaks in:
• Automobile windshields and windows
• Building windows, doors or roofs
• Valves, junctions and protective seals
• Refrigeration chamber door seals
