FLIR SI124-LD Industrial Acoustic Imaging Camera for Compressed Air Leak Detection

Call For Pricing

The FLIR Si124-LD acoustic imaging camera can help you locate pressurized leaks in compressed air systems up to 10 times faster than traditional methods. Built with 124 microphones, this lightweight, one-handed solution produces a precise acoustic image that visually displays ultrasonic information, even in loud industrial environments. The acoustic image is transposed in real time on top of a digital camera picture, which allows you to accurately pinpoint the source of the sound. The Si124-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Through a regular maintenance routine, the FLIR Si124-LD can help facilities save money on utility bills and delay the expense of installing new compressors.

Available in additional models which include a cordless battery option: the Si124-PD for electric utility applications, or the Si124 for both electric utility and leak-detection applications. View the models in the related products section below.
