The FLIR Si2x-Pro is an all-in-one, powerful tool for preventative maintenance, pre-turnaround checks, or Zone 2-rated inspections. It detects compressed air, gas leaks, partial discharges, and bearing faults from a distance of up to 200 metres.
It has AI-powered partial discharge assessment, mechanical fault analysis, and leak detection. Its wide 75° field of view, 124 microphones, and high-resolution imaging capture every detail, while built-in cost analysis tools quantify the financial impact. The camera also combines with fleet management, cloud data platforms, and OTA updates.
