Leak Detector
ULD-400-EUR Series Ultrasonic Leak Detectors
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-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 LC 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.
