FLIR IR Windows™

Anodized Aluminum or Stainless Steel Windows with PIRma-Lock™

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 barrier between you and energized equipment, protecting you from arc flash accidents.Choose the anodized aluminum frame, or opt for durable stainless steel to prevent mixed metal issues. Both are easy to install, easy to use, and will help you work with greater confidence.

FLIR IR Windows Features

Easy to Install and Use

Drill one hole and attach the single PIRma-Lock ring to hold the window in place. Simple hinged cover flips open and stays put, so you don’t need to worrying about losing, dropping, or mixing-up covers.

Stainless Steel Option

Avoid issues with dissimilar metals by choosing stainless steel model IRW-Series windows. You won’t need to worry about galvanic corrosion from contact between the stainless steel cabinet and window frame.

Broadband Transmission

FLIR’s broadband crystal lenses allow cameras to capture crisp visible and thermal images without distortions. The lenses transmit short, mid, and longwave IR, and allow laser pointers and illumination to shine through.

Safety Certified

FLIR’s IR Windows are compliant with NFPA 70E requirements, and are tested and certified for arc flash safety (KEMA)*, CSA and CSAus Model Certification, and have Underwriters Laboratories recognition (UL 50V).*IRW-2C, IRW-3C, and IRW-4C models only.
