Handheld Ultrasonic Leak Detector with Flexible Probe

Complementing ISO 10816 and ISO 20816 vibration programs, this handheld ultrasonic leak detector listens for the high-frequency airborne and structure-borne signatures produced by pressurized leaks, electrical discharge, and bearing faults. The flexible gooseneck probe reaches into cabinets, manifolds and pipework, while heterodyning brings ultrasound down into the audible band for clear identification through the supplied headset. Key Features Flexible gooseneck airborne probe with focused tip Heterodyne circuit converts ultrasound to audible range Backlit display with dB level bargraph and peak hold Adjustable sensitivity and frequency tuning Optional contact stethoscope and parabolic accessories Typical Specifications Frequency range: 20 kHz to 100 kHz (center 40 kHz) Display: backlit LCD with dB SPL readout Output: 3.5 mm headphone jack with noise-isolating headset IP rating: IP54 Battery life: 8 to 10 hr (9 V or rechargeable Li-ion) Operating temperature: 0 to 50 C Sensitivity adjustment: multi-step gain control Common Applications Compressed-air, gas and vacuum leak surveys Steam-trap and valve seat-leakage testing Bearing lubrication checks and early fault detection Electrical partial discharge and corona inspection
