You put your life at risk every time you inspect live electric components–but you don’t have to. FLIR’s IRW-Series inspection windows add a protective barrier between you and energized equipment.

You’ll perform inspections more efficiently and reduce the threat of arc flash injury, all while staying in compliance with NFPA 70E requirements.
