The FLIR Si2-LD detects and locates leaks at distances of up to 200 metres, even in hard-to-reach or hazardous areas. With 124 precision microphones, a 12MP digital camera, and 8× zoom, it provides acoustic imaging for confident leak detection. A 5-inch colour screen, auto-tuning, and ergonomic one-handed design simplify inspections in the field.
Integrated tools calculate leak size and cost, supporting accurate analysis for gases such as methane, hydrogen, carbon dioxide, ammonia, helium, and argon.
The Si2-LD includes a Mechanical Fault mode for identifying early signs of bearing wear and other mechanical issues. The No Wi-Fi variant offers the identical advanced leak detection and diagnostic performance as the standard model, but without wireless connectivity. If you require Wi-Fi connectivity, please visit our FLIR Si2-LD Industrial Acoustic Imager listing.
