Flir Si124-LD Plus Industrial Air Leak Detector
Through a regular maintenance routine, the FLIR Si124-LD Plus can help facilities save money on utility bills and delay the expense of installing new compressors, allowing you to maintain existing compressors for longer periods without sacrificing performance.
The FLIR Si124-LD Plus locates and quantifies pressurised leaks in compressed air systems—perfect for maintenance teams, manufacturing and engineering professionals. You or your team can identify air leaks up to 10 times faster than with traditional methods due to its 124 built-in microphones and the host of features including Sound Imaging, Auto Distance, and Auto Filtering.
This lightweight, one-handed solution produces a precise acoustic image; visually displaying ultrasonic information, even in loud industrial environments. This acoustic image is overlaid in real-time on a picture taken with the built-in digital camera, helping you accurately pinpoint the source of even the smallest leaks.
The FLIR Si124-LD Plus features a plugin which enables you to import acoustic images into FLIR Thermal Studio Suite for offline editing, advanced analysis, and instant report generation.
Utilising FLIR Acoustic Camera Viewer Cloud Service means analysis and reporting can be conducted out in the field, enabling efficient workflows and the ability to build fully customisable templates for routine leak detection and maintenance reporting.
