It maps ultrasonic and audible noise from 2 kHz to 100 kHz onto a live 13 MP camera image at 25 frames per second, so a compressed-air leak, a vacuum leak, or partial discharge appears as a coloured hotspot you can point to from several metres away. A 4.3 in touchscreen, on-screen analysis, laser rangefinder, and single/multi/hologram imaging modes make it quick to locate and document a source. The IP54 body, Wi-Fi and Bluetooth, and voice control suit plant walkdowns; results save as JPEG images and MP4 video. It's backed by UNI-T's nearly 40 years of test-meter manufacturing. Key Features 138-channel digital MEMS microphone array 2 kHz to 100 kHz frequency range (audible to ultrasonic) Real-time acoustic overlay on a 13 MP camera image at 25 FPS Detects compressed-air and vacuum leaks and partial discharge Laser rangefinder; detection distance 0.3 m to 150 m 4.3 in touchscreen; on-screen analyzer; single/multi/hologram modes IP54 body; Wi-Fi, Bluetooth, and voice control JPEG image and MP4 video capture to 128 GB SD UT568B Details See Sound with a 138-Mic Array An array of 138 digital MEMS microphones triangulates where a sound originates and overlays it as a colour map on the camera image — turning an inspection you'd do by ear into a picture you can point to, document, and share. Leak & Partial-Discharge Detection Covering 2 kHz to 100 kHz, the UT568B picks up the ultrasonic signatures of compressed-air and vacuum leaks and of electrical partial discharge — failures that are inaudible or hard to localize by ear, found from a safe standoff distance. Locate from a Distance A laser rangefinder and a 0.3 m–150 m detection range let you scan equipment, piping, and switchgear from the ground or a walkway, while single, multi, and hologram imaging modes suit different inspection tasks. Document & Field Use A 4.3 in touchscreen with on-screen analysis, JPEG and MP4 capture to a 128 GB card, Wi-Fi and Bluetooth transfer, and voice control make the UT568B quick to use and easy to report from on a plant walkdown. Applications Compressed-air and vacuum leak surveys in plants and utilities; partial-discharge inspection on switchgear and high-voltage equipment; energy-loss audits; and predictive-maintenance walkdowns where finding a source by ear is slow or unsafe. Frequently Asked Questions What does an acoustic imaging camera do? It uses a microphone array to locate sound and overlays it as a colour map on a camera image, so leaks and discharge appear as visible hotspots. What can the UT568B detect? Compressed-air and vacuum leaks and electrical partial discharge, across a 2 kHz–100 kHz range. How far away can it detect a source? From about 0.3 m to 150 m, with a laser rangefinder to gauge distance.
