The Ultimate Ultrasonic Diagnostic Tool

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, the use of a Transmitter (ULD-400-T) is needed to generate the ultrasonic signal. In these circumstances, it emits 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, Fluid and gas tanks, Building windows, doors or roofs.
