It seems like there isn’t a week that goes by without some manufacturer somewhere bringing out another acoustic imaging camera. Having said that, FLIR’s new model, the Si1-LD, is different. At half the price of the FLIR Si2-LD, it is equipped with 23% fewer microphones; has shortened its detection distance by 35%; and narrowed its frequency range by 23% (all compared to the Si2-LD); yet it still guarantees the same great return on investment (ROI). Obviously, we thought that sounded too good to be true, so we called Jason Cargil, FLIR’s Technical Sales Specialist, to the PASS Presents studio to prove it.

PASS Presents the NEW FLIR Si1-LD Acoustic Camera
Equipped with just 96 MEMS microphones, a 2-100 kHz frequency range, and 130m maximum detection distance, the FLIR Si1-LD Acoustic Imager, at half the price of the Si2-LD, promises an ROI that’s just as good, if not better! Consequently, the FLIR Si1-LD could revolutionise facilities maintenance, saving businesses thousands on their energy bills through quick and easy compressed air leak location and assessment; especially as the US Department of Energy estimates that industrial plants lose 20% of their compressed air capacity through leaks. New Zealand’s government puts this loss higher at 30-50%, while some independent leak auditors report losses of 80%.[1] However, all this depends on the Si1-LD Acoustic Camera delivering on all that FLIR claims. To get to the bottom of how ground-breaking the FLIR Si1-LD actually is, PASS Presents interviewed Jason Cargil, FLIR’s Technical Sales Specialist. Discover what he had to say about the FLIR Si1-LD Acoustic Camera’s accuracy, ease of use, and ROI.
