The FLIR Si2-LD pinpoints leaks from up to 200 metres away, even in complex or hazardous environments. It features 124 high-sensitivity microphones, a 12MP digital camera, and an 8Γ digital zoom to detect leaks. Its 5-inch colour display, automatic tuning, and one-handed operation make inspections quick and easy. The measurement and cost analysis tools quantify leak rates for gases such as methane, hydrogen, COβ, ammonia, helium, and argon.
Beyond leak detection, the Si2-LD has a Mechanical Fault mode that identifies bearing wear and other equipment defects. The No Wi-Fi model delivers all of the advanced leak detection and mechanical fault analysis capabilities of the standard Si2-LD, but without wireless connectivity. If you require Wi-Fi connectivity, please visit our FLIR Si2-LD Industrial Acoustic Imager listing.
