The New FLIR IRW-4C 4” InfraRed Window minimizes time and cost of complying with NFPA 70E requirements for electrical inspections!

Easy Installation
FLIR IR Windows install quickly and securely using the same design as common conduit connections:

• Only one hole to create for each window
• One simple PIRma-Lock ring nut to tighten
• Uses standard US punch tools for hole knockouts

PIRma-Lock Reliability 
Tried and true locknut technology makes FLIR's locking ring an IR window first:

• Teeth lock tight to the inside of the panel
• Automatically grounds metal components
• No screw holes required that might later strip out

Quick Access Hinged Cover
Simple thumb screw releases the permanently-hinged IR window cover:

• Easy, flip-open hatch for faster scans
• Prevents dropping, mix-ups, and loss
• Inside label for permanent identification

Broadband Crystal IR Window
Lens encased in rugged, anodized aluminum frame allows indoor and outdoor scans

• Transmits short, mid and longwave IR images
• Supports visual inspections and fusion features
• Lets laser pointers and illumination shine through

Greater Productivity and ROI

• Requires only one person instead of three
• Eliminates need for cumbersome PPE
• Helps reduce vast majority of arc flash triggers
