The FLIR Si124-PD acoustic imaging camera can help you detect partial discharge from high-voltage electrical 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 FLIR Si124-PD as it overlays acoustic images onto digital camera pictures in real time, facilitating precise sound source identification. Plus, with its plugin feature, seamlessly import images to FLIR Thermal Studio for offline editing and advanced report creation. Field analysis and reporting are made easy with FLIR Acoustic Camera Viewer cloud service. Incorporating the Si124-PD into regular maintenance routines can lead to significant utility bill savings.
