• Adjustable Receiver sensitivity for accurate leak pinpointing
• Parabola accessory directs the ultrasound towards the sensor
• Detachable Tubular Extension provides additional reach in hard to reach areas

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
