Introducing FLIR IRW-Series
for Safer, More Ef cient Electrical IR Inspections
Opening electrical cabinets to perform IR and visual inspections of
live components is dangerous work, exposing you to the risk of a
hazardous arc ash incident. Out of necessity, it’s also a painstaking,
time-consuming process.
Now you can put the added safet y of new FLIR IR Windows between
you and energized equipment to better protect yourself and eliminate
the need for opening enclosures. Much easier to install and use than
other brands, FLIR IR Windows help you work faster with greater
con dence. Perform inspections more ef ciently and reduce the threat
of arc ash injury signi cantly so you can get more done and stay in
compliance with NFPA 70E requirements.
All FLIR IR Windows feature a secure, permanently-hinged cover that
opens easily with one hand, which means there’s nothing to remove,
drop, mix up, or lose. FLIR’s broadband crystal allows cameras to
capture visible light pictures as well as thermal images and lets
LED and laser illumination pass straight through for clearer visual
assessments.
Combine FLIR IR Windows with a FLIR thermal camera that features
integrated visible light video, lamps, and a laser pointer, and you’ll be
set to get the job done single-handedly.
