Features and Benefits:

• 20 kHz to 90 kHz frequency range: optimal range for detecting a variety of leakage events
• 3 filters to remove main noise frequencies in noisy environments
• 2.5" LCD display with bargraph
• Test and locate with the transmitter unit pressurized air lines, refrigeration systems and steam lines for air leaks
• Unaffected by contaminants, or windy conditions

When equipment begins to fail due to an air or gas leak, it 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 a leak, vibration or discharge. 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. 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
