Features:

• Transmitter generates an ultrasonic signal when working in unpressurized systems
• Three Receiver filters to remove main noise frequencies in noisy environments
• Adjustable Receiver sensitivity for accurate leak pinpointing
• 20 kHz to 90 kHz frequency range: optimal range for detecting a variety of leakage events
• 2.5” LCD display with bargraph
• 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

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-420 Ultrasonic Leak Detector converts this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure. 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.
