FLIR Si2-Pro Industrial Acoustic Imaging Camera for Partial Discharge Detection, Pressurized Leak Detection and Mechanical Fault Detection

The FLIR Si2-Pro helps you significantly lower costs associated with mechanical bearing issues and partial discharge on electrical equipment. It also enables you to drastically reduce leaks in your facilities, cutting down expenses related to compressed air and gas leaks. With the Si2 series, you'll experience the best-in-class performance, decision support, fleet management, and enterprise data integration available.

For specialized needs, you can choose from additional models: opt for the Si2-LD for advanced leak detection and mechanical fault detection applications or select the Si2-PD for your electric utility applications. Explore these models in the related products section below to find the perfect fit for your requirements.
