  • Amprobe Ultrasonic Leak Detectors-1

Amprobe Ultrasonic Leak Detectors

Ultrasonic sound is a range of sound (>20kHz) that is above the human hearing capacity. Turbulence created by air or a gas forced through a small orifice generates ultrasonic sound. The ULD-300 Ultrasonic Leak Detector from Amprobe is designed to locate the source of ultrasonic sounds and leads you directly to the leak. The ULD-300 has an optical (10 LED scale) and acoustic indicator (earphone) as well as a thumbwheel for sensitivity selection.
